5.2.17 Connecting to a Relay Output Module
The Relay Output Module (ROM) provides relay outputs to switch field devices such as sounders, beacons and actuators. In
addition, an auxiliary voltage supply is available to provide power to such devices.
The relay contacts have a recommended range of ≥12 VDC, 10 mA to 250 VAC / 30 VDC 5A. The maximum contact current
rating is 5 A per channel, with the additional limitation that the maximum contact current rating for the module is 8 A. An
overcurrent protection device should be fitted to prevent higher current flowing through the relay contacts.
The auxiliary voltage supply provides DC 24 V (18–32 VDC) to the field devices at 1.5 A max. per channel, with the
additional limitation that the total current drawn from the module must not exceed 1.5 A. The supply is short circuit protected
– if a short circuit is detected the supply to all four channels is disconnected to prevent damage. The auxiliary voltage supply
will be restored automatically when the cause of the short circuit is removed.
