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.

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.

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.
