Description

The Control By Web X-WR-4R3-I is a versatile remote relay control module designed for applications requiring multiple relay outputs that can be controlled and monitored remotely via a web interface. Here are its key features and specifications:

Key Features

• Relay Outputs:
  • 4 SPDT (Form C) relays capable of handling up to 28VAC, 24VDC and 3A per relay.
  • Each relay can operate in ON/OFF mode or as a pulsed output, programmable from 0.1 to 86,400 seconds (1-day).
• Remote Control and Monitoring:
  • Built-in web server for remote access and control from any web browser.
  • Supports industrial communication protocols like Modbus TCP/IP for integration into larger automation systems.
  • Allows programming of conditional and scheduled logic via a no-code interface, simplifying complex control scenarios.
• Network Connectivity:
  • Equipped with a 10/100 Base-T Ethernet port for wired network communication.
