Description
Limit Switches, Motors, Valves, & More
The X-20S has been designed for use with controlling relatively heavy loads such as motors, solenoid valves, and lights etc.. Note: That switches can be connected to the X-20S digital inputs to enable local control of these loads. The digital inputs can also be used for other monitoring applications such as limit switches, security sensors, or light switches.
