Description

MR0 Modbus RTU RS485 IO Module – Versatile NPN/PNP Input Support for Industrial Control

The MR0 series is a high-performance Modbus RTU IO module built for industrial automation and control systems. Utilizing an RS485 communication interface, this modular system provides flexible support for digital (NPN/PNP), analog (voltage/current), and temperature (PT100) inputs. It’s compact, easy to install, and optimized for a wide variety of applications ranging from data acquisition to remote monitoring.

Key Features

• Modbus RTU Protocol (RS485): Enables stable, long-distance, and multi-device communication with configurable baud rates up to 115200.
• Flexible Input/Output Support: Modules support combinations of up to 48 digital inputs/outputs, analog channels (0–10V, 0–20mA), and PT100 temperature sensors.
• NPN/PNP Compatibility: Offers switch input support for both NPN and PNP signal types.
• High Accuracy & Resolution: 12-bit resolution for analog I/O and ±0.5°C error margin for PT100 inputs.
• Wide Operating Range: Functions reliably between -10°C to +50°C with industrial-grade EMC protection.
• Compact & Scalable Design: DIN rail mountable form factor allows for easy expansion.
