Relay coupler. Rider series, number of contacts: 2, changeover, AgCuNi, rated control voltage: 24 V DC, continuous current: 6 A, spring terminal connection. Coupling relay with forcibly guided contacts for monitoring signals in safety-relevant circuits. With a diagnostic coverage of 99%, relays with forcibly guided contacts are considered proven components in safety technology. Through the interlocking of the contacts, they ensure a synchronous switching status at both contacts. This guarantees that in the event of a fault (for example, when the working contact welds due to overload), the signaling contact maintains the same switching status.
