8AI + 18DO Industrial Modbus I/O Module – RS485, RS232 & Ethernet (RTU / TCP)

This industrial Modbus I/O module is designed for distributed data acquisition and control in automation systems. With 8 analog inputs (AI) and 18 digital outputs (DO), the unit enables flexible monitoring and control of field devices including sensors, transmitters, relays, valves, and actuators.

The module supports multiple communication interfaces:

• RS485 (Modbus RTU)

• RS232 (Modbus RTU)

• Ethernet (Modbus TCP)

This multi-protocol capability allows seamless integration into PLC systems, SCADA platforms, industrial PCs, building management systems (BMS), and remote telemetry installations.

Designed for DIN rail mounting within control panels, the module is suitable for applications including:

• Process monitoring

• Industrial automation

• Energy management

• Water & wastewater systems

• Environmental monitoring

• OEM equipment integration

The unit supports real-time acquisition of analog signals and remote switching of digital outputs through standard Modbus commands.
