X-17S™ | 4 Relay, 4 Input Expansion Module

The Go-To for Remote Applications

• X-17S

The X-17S™ expansion module is used with an X-400™ or X-600M™ controller. The four relays have Form-A contacts (SPST) and can be used to control moderate loads. Each input is optically isolated and allow the grounding system of equipment and the low-voltage circuits of the X-17S to be electrically separate. One or more X-17S expansion modules can be connected with a ribbon cable that provides both power and communication.

• 4 Relays
• 4 Digital Inputs
• Expansion Module for the X-400 and X-600M

The X-17S is a 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.
