Output Contacts
Nine isolated sets of normally open/normally closed output contacts, for Output Relays 1 - 8
and the System State Output Relay, are provided for controlling cooling equipment,
sounding an alarm, or operating remote breaker coils. Each set is capable of switching
115/230 VAC, 30 VDC @ 10 A, and the sets are accessed on Terminal Block TB1, see the
Relay Wiring figure for the Enclosure and Panel Mount monitors.
Refer to the Software Instructions for configuring the relays controlling signal, as
failsafe/non-failsafe, time delay, and other features.
Refer to the back cover of the 509ITM for configuration and identification of the output
contacts for each relay. Note that each relay is shown in the non-powered state.
Caution:
Applying high DC voltage to the output relays will damage the relays.
