Modbus Register Map
This versatile Modbus RTU I/O module provides a complete set of digital and analog channels in a single device:
-
12 dry-contact digital inputs for monitoring switches, sensors, and relays
-
6 relay outputs rated up to 220V/5A for controlling field devices
-
8 analog inputs (0–10V or 0–20mA, 16-bit resolution) for process measurement
-
2 analog outputs (0–10V or 0–20mA, 12-bit resolution) for actuator and control signal generation
Built on a 32-bit ARM processor, the module delivers stable performance, fast RS-485 Modbus RTU communication, and reliable integration with industrial control systems. Its compact DIN-rail housing, clear register mapping, and flexible 12–24V power supply make it an ideal choice for system integrators, OEMs, and automation engineers.
