The X-12s™ Eight Relay expansion module is used with the X-400 or X-600M™ controller. The X-12s has eight relays, each with Form-A contacts (SPST) with the commons tied together in two groups. A removable terminal connector provides connections to the relays.
One or more X-12s expansion modules can be connected to an X-400 or X-600M controller with a ribbon cable. The ribbon cable provides both power and communications to the expansion modules.
The X-400 or X-600M with its expansion modules such as the X-12s provide an easy, flexible and reliable way to monitor and control systems and devices over a network. The X-12s is suitable for use with moderate loads such as solenoid valves, alarms and indicator lights.
