About the Mitsubishi Electric LY42PT1P

The Mitsubishi Electric LY42PT1P is a MELSEC-L output module. Mitsubishi Electric's overview: Transistor output: 64 points, 12...24 V DC, 0.1 A/point, 2 A/common, response time: 1 ms, 32 points/common, source type, 40-pin connector x 2. Mitsubishi Electric names the MXF100-Y32P and RY42PT1P as replacement models.

What is the LY42PT1P used for?

The LY42PT1P joins a MELSEC-L system beside the CPU, with no base unit, and connects field signals to it.

Lifecycle and successor

Phased out.

OEM successor: MXF100-Y32P

Before you order

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

Check the model name LY42PT1P 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.
