Industrial Modbus I/O Module – 22 Digital Inputs & 22 Digital Outputs
Expand your control and monitoring system with this high-density industrial Modbus I/O module, featuring 22 digital inputs and 22 digital outputs with RS232 and Ethernet communications. Designed for PLC, SCADA, and automation systems, it provides reliable remote I/O expansion using standard Modbus protocols.
This Industrial Modbus Digital I/O Module is a compact and flexible solution for expanding digital input and output capacity in automation, control, and monitoring applications.
With 22 digital inputs and 22 digital outputs, the module allows large numbers of field devices—such as sensors, switches, relays, alarms, and actuators—to be connected to PLCs, RTUs, HMIs, or SCADA systems using standard Modbus RTU or Modbus TCP communication.
Multiple communication interfaces, including RS232 and Ethernet, enable easy integration into both legacy serial systems and modern IP-based networks. The module is well suited for distributed I/O architectures, remote panels, and industrial environments where reliable data exchange is essential.
Its modular design makes it ideal for factory automation, building management systems, energy monitoring, water and wastewater systems, and general industrial control.
