Installation Instructions
PLC-5 Relay Cartridge
(Cat. No. 1785-RC)
The 1785-RC Relay Cartridge serves as an interface from the PLC-5
programmable controller to a user supplied external device such as the
Allen-Bradley 700P relay. The relay cartridge contains an internal relay
contact that is opened or closed based on attempts to edit user programs or
force I/O. The user supplies 120VAC which is switched by the internal relay
for use by the external device - this may include power from ungrounded
floating systems.
