Coupling relay
Safe galvanic isolation
With the SD1K, Zander offers a very compact, safe coupling relay.

Coupling relays are used for safe, galvanically isolated contact amplification and contact multiplication as well as for filtering test pulses. The relay has a safe relay contact with a maximum switching capacity of 250V AC/DC at 6 A and a semiconductor signaling output with a width of 6.8 mm.
The SK3D has three safe relay contacts and one signaling contact with a width of 22.5 mm. In addition to seven safe relay contacts, the SR7D also offers four signaling contacts, two of which are semiconductor versions. It can also be used as a classic safety relay by rewiring. Certified use up to PL e / SIL 3 is possible.
