Description
The ControlByWeb® X-401-I is a compact dual relay and input module designed for dependable edge control in industrial, commercial, and OEM applications. As part of the 400 Series, the X-401-I combines 2 SPDT (Form C) relays with 2 optically isolated digital inputs in a versatile Ethernet-based controller that is easy to configure through a browser-based interface.
With an embedded GUI logic builder and open communication protocols including Modbus, MQTT, SNMP, and REST, the X-401-I integrates smoothly with SCADA, PLC, and IIoT systems. It is well suited for applications such as door and access control, alarm panel monitoring, network device rebooting, and motor control. Reliable, flexible, and easy to deploy, the X-401-I delivers powerful control without licensing fees or added software.
