ControlByWeb X-401™ Dual Relay & Input Modules
ControlByWeb X-401™ Dual Relay and Input Modules combine 2 SPDT (Form C) relays with 2 optically isolated inputs in a compact and robust module for industrial applications. As part of CWB's 400 Series, the X-401 modules offer a browser-based interface, embedded GUI logic builder, and open protocols (Modbus, MQTT, SNMP, REST) for seamless integration with PLC, SCADA, and IIoT systems. The lineup includes a variant with Wi-Fi® capability (X-401W) and one with cellular connectivity (X-401CW). CWB X-401 Dual Relay and Input Modules are designed for easy operation, offering immediate use with no programming required. This reliable edge-control solution eliminates licensing fees and reduces integration complexity. Ideal applications include process monitoring, equipment rebooting, event counters, electric door lock control, and alarm panel monitoring.
