Safety relay BERNSTEIN

The Rational Solution: Bernstein safety relays for all applications

Bernstein AG offers a complete range of products to suit your particular application, from the safety switch to the safety relay. Our SCR safety relays (safety gate monitoring devices) are designed to reliably monitor input signals, e. g. those generated by Bernstein limit switches, safety-switches, -interlocking switches, -rope pull switches, -sensors or two-hand controls.

Bernstein SCR relays are housed in slim-line DIN rail housings, but despite their compact dimensions they have a huge range of applications right through to control category 4 in accordance with EN 945-1.
As defined by this standard, the SCR relays monitor the correct position and reliable operation of inputs from the safety sensors or safety switch contacts. Evaluation of this information is made and the safety outputs controlling the power elements such as power contactors or frequency converters will either stop the machine in an emergency or allow re-start when safe to do so. A further check of ‘power elements’ correct stop function is made via the feedback loop.
