About the Mitsubishi Electric Q64RD

The Mitsubishi Electric Q64RD is a MELSEC-Q analogue input module. Mitsubishi Electric's overview: 4 channels, platinum resistance thermometer (Pt100, JPt100), conversion speed: 40 ms/channel, 18-point terminal block. Mitsubishi Electric names the R60TRD4-G as its replacement model.

What is the Q64RD used for?

The Q64RD mounts on a MELSEC-Q base unit and connects field signals to the CPU, which reads or writes them each cycle.

Lifecycle and successor

Phased out.

OEM successor: R60TRD4-G
