IB IL 24/48 DOR 2/W IB IL 24/48 DOR 2/W-PAC Inline Terminal With Two SPDT (Form C) Relays Data Sheet 685000 12/2003 6 8 5 0 0 0 0 1 Danger from undefined system state By default, the relay contact positions of the terminal are not defined. Power cycle (on/off) the terminal completely before connecting the segment voltage in order to avoid undesirable system states. The IB IL 24/48 DOR 2/W and IB IL 24/48 DOR 2/W-PAC only differ in the scope of supply (see "Ordering Data" on page 16). Their function and technical data are identical. The terminal must only be used in the SELV area (up to 50 V AC or 120 V DC, maximum). Features – Two SPDT (Form C) relays – Floating connections for two actuators – Nominal current of the output: 2 A – Total current of the terminal: 4 A – Diagnostic and status indicators – Segment voltage US For greater clarity, the Order Designation IB IL 24/48 DOR 2/W is used throughout this document. This data sheet is only valid in association with the IB IL SYS PRO UM E User Manual or the Inline System Manual for your bus system. Function The terminal is designed for use within an Inline station. It has two SPDT (Form C) relay contacts, Figure 1 which are independent of each other. 685000 6 8 5 0 0 0 0 2 IB IL 24/48 DOR 2/W-PAC 1 IB IL 24/48 DOR 2/W (-PAC) Special Features of the IB IL 24/48 DOR 2/W Terminal Switching a Voltage Equal to the Segment Voltage Switching a Voltage Unequal to the Segment Voltage The potential US is available at the terminal points 1.1 and 1.2. – Inserting a jumper between 1.1 and 1.3 or 2.1 and 2.3 enables connecting the segment voltage potential to the main contact of the relevant relay in order to switch the load in a non-floating manner. Different DC voltages Distance terminals are not required. Inserting a jumper is not useful and not permitted. It is only permitted to switch the load in a floating manner. If the switch contact potentials and the segment circuit potential are two different DC circuits, Phoenix Contact recommends using a ground connection between the two power supply units. If no jumpers are inserted, switching the load can also be floating. – Switching an AC voltage within a DC segment circuit Distance terminal must be used. The distance terminals interrupt the potential jumpers. As a result, no segment voltage is present at the terminal points 1.1 and 2.1. It is only possible to switch the connected load in a floating manner. When switching voltages outside the SELV area, use the Inline terminals IB IL 24/230 DOR 1/W or IB IL 24/230 DOR 4/W. 2 685000 IB IL 24/48 DOR 2/W (-PAC) General Description Local Diagnostic and Status Indicators Des.

As the distance terminals interrupt all the potential jumpers, US is not available at the terminal points 1.1 and 2.1 in this case. In this case the connected load can only be switched in a floating manner. 6 When using several IB IL 24/48 DOR 2/W terminals Phoenix Contact recommends creating a separate main circuit with separate supply. 685000 IB IL 24/48 DOR 2/W (-PAC) Interference Suppression Measures on Inductive Loads/ Switching Relays Each electrical load is a mixture of ohmic, capacitive, and inductive elements. Depending on the proportion of the element, switching these loads results in a larger or smaller load on the switch contact. In practice, loads are generally used with a large inductive element, such as contacts, solenoid valves, motors, etc. Due to the energy stored in the coils, voltage peaks of up to several thousand volts may occur when the system is switched off. These high voltages cause an arc, which may destroy the controlling contact through material evaporation and material transfer. This pulse, which is similar to a square wave pulse, emits electromagnetic pulses over a wide frequency range with a large amount of power and with spectral elements reaching several MHz. To prevent such arcs from occurring it is necessary to fit the contacts/loads with protective circuits. The following protective circuits can be used: – Contact protective circuit – Load protective circuit – Combination of both protective circuits 685000 A B 5 9 7 3 A 0 2 8 Figure 8 Contact protective circuit (A), load protective circuit (B) If sized correctly, these circuit versions do not differ greatly in their effectiveness. In principle, a protective measure should be directly implemented at the source of the interference. The following points speak in favor of a load protective circuit: – When the contact is open, the load is electrically isolated from the operating voltage. – It is not possible for the load to be activated or to "stick" due to undesired operating currents, e.g., from RC elements. – Shutdown voltage peaks cannot be coupled in control lines that run in parallel. Phoenix Contact provides protective circuit solutions in terminal format or in electronic housing (see the "CLIPLINE" catalog or "TRABTECH" catalog). Additional information is available on request. In addition to this, today the majority of contactor manufacturers offer diode, RC or varistor elements that can be snapped on. For solenoid valves, connectors with an integrated protective circuit can be used. 7 IB IL 24/48 DOR 2/W (-PAC) Circuit Versions L o a d P r o te c tio n D io d e A d d itio n a l D e la y D e In d V o L im fin e d u c tio n lta g e ita tio n B ip o la r E ffe c tiv e A tte n u a tio n + U L o a d D L o n g Y e s (U D ) N o A d v a n ta g e s /D is a d a v a n ta g e s A d v a n ta g e s : - e a s y im p le m e n ta tio n - c o s t- e ffe c tiv e - r e lia b le - u n c r itic a l d im e n s io n in g - lo w in d u c tio n v o lta g e D is a d v a n ta g e s : - a tte n u a tio n o n ly v ia lo a d r e s is to r - lo n g o ff d e la y S e r ie s c o n n e c tio n d io d e /z e n e r d io d e + L o a d U M e d iu m to s h o rt A d v a n ta g e s : - u n c r itic a l d im e n s io n in g Y e s (U ) Z D N o Z D S u p p r e s s o r d io d e + (~ ) (~ ) U L o a d Z D M e d iu m to s h o rt Y e s (U Z D ) Y e s D is a d v a n ta g e s : - a tte n u a tio n o n ly a b o v e U Z D A d v - c o - u n - lim - s u a n ta g e s : s t- e ffe c tiv e c r itic a l d im e n s io n in g ita tio n o f p o s itiv e p e a k s ita b le fo r A C v o lta g e D is a d v a n ta g e s : - a tte n u a tio n o n ly a b o v e U Z D V a r is to r + (~ ) (~ ) L o a d V D R U V D R M e d iu m to s h o rt Y e s (U V D R ) Y e s A d - h - u - s v a n ta g ig h p o w n c r itic a u ita b le e s e l d fo : r a b s o r p tio n im e n s io n in g r A C v o lta g e D is a d v a n ta g e s : - a tte n u a tio n o n ly a b o v e U V D R 5 6 6 3 A 0 2 9 8 685000 IB IL 24/48 DOR 2/W (-PAC) RC Circuit Versions RC Connected in Series: A d d itio n a l O ff D e la y L o a d P r o te c tio n D e In d V o L im fin e d u c tio n lta g e ita tio n B ip o la r E ffe c tiv e A tte n u a tio n A d v a n ta g e s : - H F a tte n u a tio n - s u ita b le fo r A C - le v e l- in d e p e n d - r e a c tiv e - c u r r e n R /C c o m b in a tio n + (~ ) (~ ) R U L o a d M e d iu m to s m a ll R C A d v a n ta g e s /D is a d v a n ta g e s N o v ia p v o lta e n t a t c o m o w e r s to ra g e g e tte n u a tio n p e n s a tin g Y e s D is a d v a n ta g e s : - e x a c t d im e n s io n in g r e q u ir e d - h ig h in r u s h c u r r e n t C 5 6 6 3 A 0 3 0 Sizing: – Capacitor: C LLoad/4 RLoad2 – Resistor: R 0.2 RLoad RC Parallel Circuit With Series Diode A d d itio n a l O ff D e la y L o a d P r o te c tio n D e In d V o L im fin e d u c tio n lta g e ita tio n B ip o la r E ffe c tiv e A tte n u a tio n A d - H - le - C R /C c o m b in a tio n w ith d io d e + (~ ) (~ ) U L o a d R C M e d iu m to s m a ll C A d v a n ta g e s /D is a d v a n ta g e s N o Y e s v a n ta F a tte v e l- in u rre n g e s : n u a tio n v ia p o w e r s to r a g e d e p e n d e n t a tte n u a tio n t in v e r s io n n o t p o s s ib le D is a d v a n ta g e s : - e x a c t d im e n s io n in g r e q u ir e d - o n ly s u ita b le fo r D C v o lta g e R 5 6 6 3 A 0 3 1 Sizing: – Capacitor: C LLoad/4 RLoad2 – Resistor: R 0.2 RLoad 685000 9 IB IL 24/48 DOR 2/W (-PAC) Switching AC/DC Loads Switching Large AC Loads 3 .0 A 2 .0 When switching large AC loads, the relay can be operated up to the corresponding maximum values for switching voltage, current, and power. The arc that occurs during shutdown depends on the current, voltage, and phase angle. This shutdown arc switches off automatically the next time the load current passes through zero. IL Switching Large DC Loads In DC operation, a relay can only switch a relatively low current compared with the maximum permissible alternating current. This maximum direct current value is also highly dependent on the voltage and is determined in part by design conditions, such as the contact distance and contact opening speed. The corresponding current and voltage values are shown using the example in Figure 9. 2 0 .3 In applications with an inductive load, an effective protective circuit must be provided, otherwise the life of the system will be reduced considerably. To prolong the life of the IB IL 24/48 DOR 2/W terminal as much as possible when using lamp loads or capacitive loads, the current peak must not exceed 2 A when the load is switched on. 1 1 .0 0 .1 1 0 1 0 0 V 2 0 0 3 0 U S w itc h 6 8 5 0 0 0 1 0 Figure 9 DC load limiting curve (REL-SNR-1XU/G 5 GOLD LIEG relay) I Switching current in A U Switching voltage in V Definition of the load limiting curve: For 1000 cycles, no constant arc should occur with a burning life of >10 ms. An unattenuated inductive load further reduces the values for switching currents given here. The energy stored in the inductor can cause an arc to occur, which forwards the current via the open contacts. Using an effective contact protective circuit, the same currents can be switched as for an ohmic load and the life of the relay contacts is the same. If it is permitted to switch higher DC loads, several relay contacts can be switched in parallel.
