Modbus Digital I/O Module – 23 Digital Inputs & 24 Digital Outputs
High-density industrial I/O expansion for PLCs, RTUs, and SCADA systems. This Modbus digital I/O module provides 23 digital inputs and 24 digital outputs with reliable RS485/RS232 communication for automation and control applications.
This industrial Modbus digital I/O module is designed for reliable expansion of digital inputs and outputs in automation, monitoring, and control systems. Featuring 23 digital inputs (DI) and 24 digital outputs (DO), it allows high-density signal acquisition and control from a single compact device.
The module communicates via RS485 and RS232 using the widely supported Modbus RTU protocol, ensuring easy integration with PLCs, HMIs, RTUs, gateways, and SCADA platforms. It is well suited to distributed control systems where stable communication, fast response, and simple addressing are required.
Built for industrial environments, this I/O module is ideal for factory automation, building management systems, energy monitoring, and process control where multiple digital signals must be handled efficiently and reliably.
