Open Collector
Flip to OFF the shunt resistor DIP switch for the input you want to modify and flip to ON the pull-up resistor
DIP switch.
Attach the open-collector sensor to the input screw terminals. Use the INP S command to configure the input
for a dry-contact sensor (refer to the Command Reference section).
110/220 VAC
Caution: An interposing relay MUST be used to monitor 110/220 VAC signals.
Flip to OFF the shunt resistor DIP switch for the input you want to modify and flip to ON the pull-up resistor
DIP switch.
Wire the 110/220 VAC signal to the coil of a suitably rated relay. Wire the relay contacts to the input screw
terminals. Use the INP S command to configure the input for a dry-contact sensor (refer to the Command
Reference section).
Other
To connect a thermocouple, millivolt or other type sensor to the OMA-D560, use an appropriate signal
conditioner. Contact technical support for assistance.
Connecting the Outputs
The OMA-D560 has four outputs that can be controlled remotely or automatically in response to alarm conditions
or input parameters. The control capabilities of these outputs are described in the “Control” section of this manual.
„ Output Relays
Each of the four outputs is capable of switching 5 amp loads. Note: When switching voltages in excess of 30
volts, the OMA-D560 must be placed in an approved enclosure.
„ Switched AC Outlet
You can also plug equipment (seven amp maximum load) into the “Switched AC” power outlet located on the
side of the unit (110 VAC units only). This switched outlet works in unison with the output 1 relay on the front
panel.
