RELAYGO

COIL CIRCUIT ACCESORIES

As a relay is managed by transistors, triacs, etc…, it is required to adopt protection measures, peaks might appear in the line, motor switching, electrovalves, transformers, capacitors, etc…, on the other hand, as the coil disconnects, inverse voltage peaks appear, and they can create high pulses that are transmitted to other devices connected to the Coil line.
Normally a relay is unaffected by these pulses, but if a diode is connected in association with the coil, it must be cap- able of withstanding an inverse voltage higher than those of the incoming peaks.
RelayGO relays can be manufactured with protection circuits, decreasing or blocking coil generated pulses, as well as block line peaks.
