Mitsubishi A64RD3C Temperature Input Module for MELSEC Series

The Mitsubishi A64RD3C (A64RD3C) is a temperature input module manufactured by Mitsubishi Electric for use in industrial programmable logic controller systems. As part of Mitsubishi's specialized automation hardware, this discontinued module is designed to integrate temperature sensing and process monitoring into industrial control architectures. In legacy documentation and mixed-unit cross-references, the unit has also been documented alongside combined I/O configurations including 48 digital inputs and outputs featuring 24 V DC digital inputs and normally open relay contact outputs within Mitsubishi Electric MELSEC series environments. Operating within factory automation and machine control setups, the module provides signal processing and interfacing essential for automated manufacturing, thermal regulation, and machine sequencing. Built to industrial manufacturing standards, the A64RD3C delivers dependable performance for replacement, maintenance, and retrofit projects in legacy Mitsubishi Electric PLC installations where maintaining original controller hardware is vital.
