About the Mitsubishi Electric QY18A

The Mitsubishi Electric QY18A is a MELSEC-Q output module. Mitsubishi Electric's overview: Contact output: 8 points, 24 V DC/240 V AC, 2 A/point, response time: 12 ms, all points independent common, 18-point terminal block. Mitsubishi Electric names the RY18R2A as its replacement model.

What is the QY18A used for?

The QY18A 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: RY18R2A
