Force-guided safety relay

Gurnee, Ill. —Standard force-guided contact designs ensure if a make contact is welded closed, the break contacts can not re-close. The H-470 adds a mechanical actuator to ensure if a break contact welds closed, all other break contacts are forced open, and make contacts cannot re-close. This design guarantees added safety for circuits where fail-safe deterministic behavior is required, ...

Gurnee, Ill. —Standard force-guided contact designs ensure if a make contact is welded closed, the break contacts can not re-close. The H-470 adds a mechanical actuator to ensure if a break contact welds closed, all other break contacts are forced open, and make contacts cannot re-close. This design guarantees added safety for circuits where fail-safe deterministic behavior is required, such as, elevator controls, press controls, light curtains, and pressure mats.
