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.
