Expansion Module 4 Relays 4 Inputs
The ControlByWeb X-17S™ expansion module is used with either the X-400™ or X-600M™ controllers. The 4 onboard relays have Form-A contacts (SPST) and can be used to control moderate loads. Each input is optically isolated and allows the grounding system of equipment and the low-voltage circuits of the X-17S to be electrically separate. One or more X-17S expansion units can be connected with a ribbon cable that provides both power and communications via the BUS.

Description
The Smart Go-To for Remote Applications
The ControlByWeb X-17S is a highly versatile expansion module, offering the flexibility to monitor sensors and control devices over a network when paired with the X-400 or X-600M. Common applications include center pivot, simple tank monitoring, and moderate-light loads like solenoid valves, alarms, and indicator lights.
