The Mitsubishi A68RD4 is a high-precision temperature sensor input module designed for integration with Mitsubishi PLC systems. This module is specifically engineered to support Pt100 and JPt100 platinum resistance thermometers, conforming to JIS and DIN standards. The A68RD4 utilises a 4-wire measurement system, ensuring accurate temperature readings by compensating for lead wire resistance.

With a robust design, the A68RD4 offers reliable performance in industrial environments. It features 8 input channels, each capable of detecting temperature ranges from -180°C to 600°C. The module outputs temperature values in 16-bit signed binary data, providing precise and detailed measurements.

The A68RD4 is equipped with advanced functionalities such as disconnection detection, which identifies any disconnection in the platinum resistance thermometer or conductor. Additionally, it allows for conversion enable/disable settings for each channel, optimising sampling time and preventing unnecessary detections on unused channels.

This module is designed with a compact form factor, making it suitable for various industrial applications where space is a constraint. It also includes a 38-point terminal block for secure and straightforward connections. The A68RD4's insulation method ensures safety and reliability, with photocoupler-insulated inputs and a dielectric withstand voltage of 500VAC for one minute.

Ideal for industries requiring precise temperature monitoring and control, the Mitsubishi A68RD4 temperature sensor input module is a dependable choice for enhancing the capabilities of your PLC system.
