Modbus RTU RTD Remote I/O Module – 4/8 Channel Temperature Data Acquisition

Overview

The Modbus RTD Remote I/O Module is designed to simplify temperature data acquisition in large-scale industrial projects. By placing these modules close to the sensors, you eliminate the need for long, expensive runs of shielded RTD cable, as all data is transmitted digitally via a simple 2-wire RS485 bus. It supports standard industrial communication protocols, ensuring seamless integration with virtually any PLC or SCADA software.

Key Features

• Universal Compatibility: Supports most common RTD types, including PT100 and PT1000.

• Long-Distance Transmission: RS485 Modbus communication allows for reliable data transfer over hundreds of meters.

• High Precision: Built-in high-resolution ADC ensures accurate temperature readings with minimal noise.

• Galvanic Isolation: Protects your PLC and control system from voltage spikes and ground loops common in industrial environments.

• Easy Addressing: Configurable via software, allowing multiple modules to be daisy-chained on a single bus.
