4 Digital Input to RS485

The 4-Digital Input to RS485 Remote I/O Module is a input acquisition device designed for monitoring multiple digital signals in industrial automation systems. It supports Modbus RTU protocol over RS485 communication, enabling seamless integration with PLCs, SCADA, HMI, and DCS systems.

With 4 optically isolated digital inputs, the module is ideal for monitoring switches, sensors, limit sensors, proximity sensors, and dry contact devices in real-time. It supports half-duplex communication with cost-effective two-wire connectivity, making it suitable for distributed monitoring applications.

This device provides robust communication, strong electrical isolation, and industrial-grade reliability, making it suitable for factory automation, energy management, building control, and input monitoring applications.
