About the Mitsubishi Electric QY50

The Mitsubishi Electric QY50 is a MELSEC-Q output module. Mitsubishi Electric's overview: Transistor output: 16 points, 12...24 V DC, 0.5 A/point, 4 A/common, response time: 1 ms, 16 points/common, sink type, 18-point terminal block. Mitsubishi Electric names the RY40NT5P as its replacement model.

What is the QY50 used for?

The QY50 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: RY40NT5P

Before you order

What to photograph or confirm so the right unit is quoted.

Check the model name QY50 on the rating plate, with the serial number and function version. Send us a photo of the rating plate and we will confirm the details before quoting.
