HT1B & HT2B - DC Current Transformers / Transducers - Torroidal

Quick Overview

A torroidal transducer that operates on the hall effect principle to measure DC current and provide a proportional analogue output. The HT1B has a 35mm diameter aperture, the HT2B 80mm, through which the conductor is passed. An auxiliary supply is required. Where current output is specified, a dipswitch allows the user to select either 0-20mA or 4-20mA. Both models may be mounted on DIN rail by means of an optional clip.
