SCR Safety Relais From Signalling to Evaluation – Responsable Solutions for Safety Applications 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. 13 23 33 41 A1 S34 S33 S12 13 Power Channel 2 Channel 1 S21 S22 S11 A2 14 24 34 42 23 33 41 A1 S34 S33 S12 13 23 33 43 A1 U1 Y1 Y2 S21 S22 A2 31 47 48 S21 S22 A2 31 47 48 A1 S11 S12 32 57 58 A1 S11 S12 32 57 58 Power Power Stop Channel 2 Channel 2 Ch. 1 Channel 1 Channel 1 Ch. 2 S21 S22 S11 A2 K1 K21 U22 A2 14 14 24 34 42 24 34 44 Power Time 1 Ch. 1 Time 2 Ch. 2 Ch. 3(t) Ch. 3(t) Ch. 4(t) Ch. 4(t) Time 1 Time 2 S10 S33 13 14 S10 S33 13 14 S35 S34 23 24 S35 S34 23 24 Des.: SCR 4-W22-3.5-D Art.

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.
