Output Relay Wiring
Relay outputs are provided for connecting to customer-supplied devices. Each
output relay can provide general purpose low or intermediate power control to the
device. The relay will switch 2A at 30 VDC.
All outputs supply a normally open, common,
and normally closed relay contact.
The state of each relay is indicated by a red LED adjacent to each set of relay contact
outputs. The LED is lit when the relay is energized.
