X-20s™ | 6 Relay, 6 Digital Input Expansion Module
The X-20s expansion module has 6 relays and 6 digital inputs which can be accessed through an X-400 or X-600M controller.
Overview
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.
The X-20s is suitable for use with controlling relatively heavy loads such as motors, solenoid valves, and lights. Switches can be connected to the X-20s' digital inputs to locally control these loads. The digital inputs can also be used for other monitoring applications such as limit switches, security sensors, or light switches.
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.
Other expansion modules with different I/O combinations are also available.
