The X-17s™ expansion module is used in conjunction with the X-600M controller. The X-17s is a multi-function module with four relays and four optically-isolated digital inputs. One or more X-17s expansion modules can be connected to an X-600M controller with a ribbon cable which provides both power and communications.

The four relays have Form-A contacts (SPST) and can be used to control moderate loads such as solenoid valves, alarms and indicator lights.
