Signal converters & Isolators

Introduction & Selection Guide

INTRODUCTION

Process control and monitoring systems often utilise a large number of standard process signals; Voltage levels, current loops, temperature and pulsed signals to name but a few. When designing a system from scratch it may be possible to exactly match each type of sensor to a controller, but even then it is not allways cost effective to do so.

Industrial plcs and other controllers tend to be built in modular form, so to purchase a block of 8 analogue inputs just to cope with 1 analogue signal can be a very expensive exercise. When it comes to modifying existing systems, the problem becomes even worse. A substantial rebuild of the system is often necessary just to provide the facillity of 1 or 2 extra inputs.Fortunately, a simple, cost effective solution is at hand - the PX range of treshold and signal converters.

With Brodersen PX Process Industrial signal conditioners, signals can be converted from one standard to another and even an analogue signal can be effectively fed into a digital input. The PX Signal Conditioner is a high quality product which has been designed and tested to the latest requirements for EMC immunity/emission and the low voltage directive (CE marked).

The PX Signal Conditioner also provides a galvanic isolation of

3.75kV. The PX relay is of a new design, supplied in a standardised

industrial housing, 22.5mm wide, for mounting on 35mm symmetrical

DIN-rail with touch-proof, combi notch-screw terminals.

A snap-on cover on the front of the relay conceals the adjustment

potentiometres.
