About the Mitsubishi Electric QY70

The Mitsubishi Electric QY70 is a MELSEC-Q output module. Mitsubishi Electric's overview: Transistor output: 16 points, 5...12 V DC, 16 mA/point, 256 mA/common, 16 points/common, sink type, 18-point terminal block. Mitsubishi Electric lists it as discontinued since 2026/03, with repair support until 2033/03. Mitsubishi Electric names the RY41NT2H as its replacement model.

What is the QY70 used for?

The QY70 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: RY41NT2H
