About the Mitsubishi Electric Q68DAI

The Mitsubishi Electric Q68DAI is a MELSEC-Q analogue output module. Mitsubishi Electric's overview: 8 channels, input (resolution): 0...4000, -4000...4000, 0...12000, -12000...12000, output: 0...20 mA DC, conversion speed: 80 μs/channel, 18-point terminal block. Mitsubishi Electric lists it as discontinued since 2007/12. Mitsubishi Electric names the R60DAI8 as its replacement model.

What is the Q68DAI used for?

The Q68DAI mounts on a MELSEC-Q base unit and connects field signals to the CPU, which reads or writes them each cycle.

Lifecycle and successor

Discontinued.

OEM successor: R60DAI8
