The X-11s 2-relay expansion module is used with the X-400 or X-600M™ controller. The X-11s has two high-power relays (250 Vac, 20 A). 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-400 or X-600M control module with a ribbon cable. The ribbon cable provides both power and communications to this and other expansion modules.
