The R44 is a versatile and compact I/O module featuring 4 isolated digital inputs and 4 relay outputs, designed for industrial automation systems. It communicates with the central controller via the Modbus RTU protocol over RS-485 network, enabling full configuration, monitoring, and control capabilities directly through software.
With isolated inputs for receiving digital signals and relay outputs for controlling external devices, the R44 module provides a complete solution for managing industrial processes. The Modbus RTU protocol allows for flexible addressing and reliable communication within distributed control systems.
This module is ideal for smart monitoring systems, remote control, industrial automation, security systems, smart greenhouses, and energy management. The integration of both inputs and outputs in a single unit makes it an efficient and practical choice for equipment control, sensor status monitoring, and industrial process management.
