Product Description

Overview

The Schneider MET148‑2 is an external temperature sensor module designed for Sepam Series 20, 40, and 80 protection relays. It allows direct temperature measurement using Resistance Temperature Detectors (RTDs) such as Pt100, Ni100, and Ni120. Moreover, this module can be connected during installation, commissioning, or maintenance, providing flexible integration with existing protection systems. The compact, screw-terminal design ensures quick installation without additional power supplies, as it is powered directly by the Easergy P5 relay.
