ID5SI-2 SIGNAL ISOLATOR / RUN RELAY for use with ID5601 Inverters Signal Isolator: Provides isolation between non-isolated signal sources and the Inverter Run Relay: Used to turn on or off equipment or signal a warning if a fault has occurred STANDARD FEATURES • Isolated Switching: Provides isolation for PLC open collector or contact switching. • Isolated +5V Power Supply: Used to power a transducer or to supply voltage for potentiometer operation. • Power On LED. TRIMPOT ADJUSTMENTS (Multi-Turn) • Maximum Speed (MAX) • Minimum Speed (MIN) JUMPER SELECTABLE FEATURES • J1 (VOLT/CUR): Selects voltage or current signal input. • J2 (NO/NC): Selects normally open or normally closed relay contacts at Terminal Block TB2. OPTIONAL ACCESSORY • Auto/Manual Switch (ID5AMS-1): Selects a signal input from either the ID5SI-2 Signal Isolator or the Main Speed Potentiometer. DESCRIPTION The ID5SI-2 is used with the ID5601 Inverter series inverters to isolate, amplify and condition DC voltage and current signals from any source (tach-generators, transducers, PLCs and potentiometers). It also provides an isolated input to control motor direction and an isolated power supply for transducer or potentiometer operation. All input connections are isolated from the AC line and motor wiring. The ID5SI-2 installs easily into the Inverter with a snap-in mounting base and is wired with quick-connect terminals. The main features of the ID5SI-2 include voltage or current signal inputs and a Run Relay which is used to turn on or off equipment or signal a warning if a fault has occurred. Other features of the ID5SI-2 include a power on LED, barrier terminal blocks to facilitate wiring, multi-turn trimpots (MAX, MIN) and selectable jumpers for signal input selection and Run Relay output contacts. An optional accessory for use with the ID5SI-2 and the ID5601 Inverter is an Auto/Manual Switch (ID5AMS-1) which selects a signal input from either the ID5SI-2 Signal Isolator or the Main Speed Potentiometer.
