4-RELAY OUTPUT MODULE INSTALLATION GUIDE 1 - Product Overview The xRO 4-Relay Output Module is typically ordered as an option to the #4202 and #4204 Power Supply units. This component is also available as a separate device when sold for installation in a customer’s enclosure. 20 21 22 24 23 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 SPARE 1 2 3 4 5 6 8 7 9 10 11 12 13 14 15 16 17 18 19 Applications The 4-Relay Output Module can be used to control maglocks, electric strikes or other low voltage devices. This equipment is frequently used for power isolation between devices controlled from a common point. The xRO board can also be used to disconnect power to selected devices when the on-board Auxiliary Relay is configured to override the trigger inputs controlling the four DPDT relays. Other special applications can include door interlocks. Features Universal Dual Voltage - The xRO board will operate on 12 or 24 VDC without modification. Trigger inputs accept dry contacts to ground relay coils when triggered. Heavy Duty Fused Outputs – Relay contacts are DPDT rated for 3amps at intermittent or continuous duty. One common is fused on one contact of each DPDT relay. (fuses are rated @ 1.6Amps) Four DPDT relays and one SPDT relay are each individually triggered by closure of a normally open dry contact. LED indicators are provided to show when each of the DPDT relays are energized. The xRO Board can be by mounted with stand-offs or with 3” wide snap-track. On-board jumpers allow relays to be individually configured for control override by the AUX relay. 1 2 - Technical Specifications Electrical Input Power – 12 or 24 VDC Current Draw - 30 mA @ 12/24 VDC (Relays inactive) 150mA @ 12/24 VDC (Relays activated) Relay Coils – 5 VDC (from on-board source) Relay Contacts – DPDT @ 3 amps Mechanical 3” x 9” Circuit Board – For mounting by stand-offs or snap-track Three 2-Position Terminal Strips – 12 to 26 AWG Five 3-Position Terminal Strips – 12 to 26 AWG Four 6-Position Terminal Strips – 12 to 26 AWG Five LED Indicators – DC Power & Relay Activation Options Single and multiple relay modules may be configured to provide door interlock controls in many different configurations. Please contact the factory for additional information regarding these special applications. Warranty Dortronics standard one year warranty on electronic control devices provides for replacement of products with manufacturing defects. Advance replacement of parts under warranty is provided to customers with an open credit account. 3 - Installation These relay modules are typically sold as a power supply option. They are factory installed in the NEMA enclosure with the other power supply components as a complete assembly. Large screw terminal strips allow multiple conductors to be easily wired to the module. Settings & Adjustments The “jumpers” are factory installed to perform the functions required. Custom Configurations Contact Factory Precautions If using a power source in excess of 4 amps, do not allow the total current draw on a single set of relay contacts to exceed the 3 amp rating. Do not remove or change the factory installed jumpers without consulting the factory. If utilizing multiple boards in a customer designed configuration contact factory. 2
