The Safety Relay is a type of PCB Relay manufactured by Dold suitable for use on printed circuits.
These relays are equipped with a positive guided contact, with at least one closed and one open contact. The contacts are never closed together. If a normally open contact is soldered, the closed contact will not be closed when the supply voltage is shut off.
The safety relay has a contact distance of 0.5mm. The device features a primary monitoring function to determine if there is a contact breakdown, ensuring long operating life.
The relay is designed for fuel technology and railway applications. It also provides safety for operations involved in the machine- or plant-building sector.
