Relay RT590 Connector
The relay terminals on the 130-MC provides three relay closures for certain software set able
alarm conditions. Both Normally Open and Normally Closed contacts are provided on the relay
connector for each of the three relays. A hardware jumper is provided to change the relay
contacts from
Normally
De-energized
(default) to
Normally
Energized
. The relay contacts are
rated at 120 Volts AC and 30 Volts DC. The relay amp rating is equal to 1 amp. These alarm relays
can be configured using the RL command or on the Relay section of the GUI. See the
SMCC Users
Guide
or
Command Line Reference
for more information.
