32-Channel Digital Input Module – RS485 Modbus RTU Industrial I/O Acquisition
High-density 32-channel digital input (DI) module with RS485 Modbus RTU communication, designed for reliable signal acquisition from switches, sensors, and dry contacts in industrial automation systems.
This 32-channel digital input I/O module is built for industrial environments requiring high input density, stable communication, and long-distance transmission. Using RS485 with Modbus RTU, it integrates seamlessly with PLCs, RTUs, SCADA systems, HMIs, and industrial gateways.
The module is ideal for applications such as status monitoring, alarm collection, equipment feedback, and process control, where a large number of digital signals must be collected efficiently and reliably.
