The easiest and simplest devices for measuring current


- Safe & simple current measurement


- for retrofit installation just clip SXDs around the cable


- for new installation, no need for CTs, clip XDs onto the rail & pass the cable through the hole


- current measurement - 4-20mA or 0-5Vdc outputs - mean sensing or true RMS


- energy management - pulse output meter replacement


- earth leakage measurement - 4-20mA true RMS from 5mA (XD-R420-0)


- motor control ON / OFF and failure sensing


- actuators - operation / failure


- lamp failure - multiple lamps can be monitored with a single XD



the simplest device possible for measuring current. For minimising stocking, each transducer may be connected for 5 Amp or 1 Amp input. Neat slim and easy to use. Applicatons include:


- Motor Control

- Failure Detection, including

Heating Coils

Lighting Circuits


- Energy Management


Control Systems


Where the application is for lower or higher currents, the XD range of transducers can directly measure currents from 5mA to 250 Amp.
