Description

Product Overview

The MTL4532 is a backplane‑mounted three‑port galvanically isolated pulse/frequency interface for hazardous area flow, turbine, encoder, pulse transmitter and NAMUR proximity sensors. It accepts pulse input from zone 0/1/2, delivers simultaneously: solid‑state pulse output, 4–20 mA frequency‑to‑current conversion, plus relay line fault alarm. Fits the CPS16 backplane you queried before.
