High-Current Relay Expansion Module | X-11s
5 Year Warranty

X-11s expansion module with two high-current relays can be controlled over the internet with an X-400 or X-600M controller.


The X-11s 2-relay expansion module is used with an X-400 or X-600M controller. The X-11s has two high-current relays. Both relays have Form-C contacts (SPDT). A rugged, high-current connector provides connections to the relays.

One or more X-11s expansion modules can be connected to an X-600M control module with a ribbon cable. The ribbon cable provides both power and communications to this and other expansion modules.

The X-400 or X-600M with its expansion modules such as the X-11s provides an easy, flexible, and reliable way to monitor and control systems and devices over a network. It is suitable for use with loads which require line voltages and high currents such as pumps, motors, lights and heaters.

Other expansion modules with different I/O combinations are also available.
