This security control relay Wieland Electric consumes less energy than a standard equivalent component. Samos PRO control relay has a CPU and can manage 96 safety inputs and 48 safety outputs.

Ignored for a long time, the electricity consumption of equipments and panel automation has begun to interest manufacturers and some contractors. Until now, the few Watts lost in thermal heating by a circuit breaker or an automat had been going almost unnoticed in a world without energy balance.

Today, manufacturers attitudes are changing and their R&D teams are working on this subject. The low-energy impact intrinsic to the equipment sometimes also becomes a sales argument. (more…)
