The X-20s™ expansion module is used with an X-400 or X-600M controller. The X-20s has six, high-current relays, each with Form-C contacts (SPDT) and six, optically-isolated digital inputs. A screw terminal strip provides high-current connections to the relays.
Since the X-20s functions as a slave device to the X-400 or X-600M controller, the advanced features of the controller can be utilized with this module. For example scheduling, remote relay control, logging, counting, email alerts based upon single input state change or multiple input state changes, and many other features are available. Attach multiple X-20s 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.
The X-20s comes with a 5-inch jumper type ribbon cable for making connections to the X-400 or X-600M.
