About the Mitsubishi Electric LY18R2A

The Mitsubishi Electric LY18R2A is a MELSEC-L output module. Mitsubishi Electric's overview: Contact output: 8 points, 24 V DC/240 V AC, 2 A/point, 8 A/module, response time: 12 ms, all points independent common, 18-point terminal block. Mitsubishi Electric names the RY18R2A and FX5-8EYR/ES as replacement models.

What is the LY18R2A used for?

The LY18R2A joins a MELSEC-L system beside the CPU, with no base unit, and connects field signals to it.

Lifecycle and successor
