About the Mitsubishi Electric Q64RD-G

The Mitsubishi Electric Q64RD-G is a MELSEC-Q analogue input module. Mitsubishi Electric's overview: 4 channels, RTD (Pt100, JPt100, Ni100), conversion speed, 40 ms/channel, 18-point terminal block, channel isolated. Mitsubishi Electric names the R60TRD4-G as its replacement model.

What is the Q64RD-G used for?

The Q64RD-G 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
