The X-18s™ expansion module is used with an X-400 or X-600M controller. The X-18s has ten, high-current relays, each with Form-C contacts (SPDT). Wiring connections are made directly to the relays using 1/4″ tab terminals located on top of the relays.

This module is suitable for use with loads which require line voltages and high currents such as pumps, motors, lights and heaters. Attach multiple X-18s modules or a combination of expansion modules to the X-400 or X-600M for an I/O combination that is tailored to your specific needs.

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