With its H-464 safety relays, HENGSTLER provides a solution for all those applications that involve a high number of electric switching contatcts. The safety relay is designed for the highest possible degree of reliability, robustness and a long electrical life-time. As a result, these safety relays can be used wherever high availability is essential, even at high switching loads. The DC drive system can be supplied as either a monostable or a bistable version. For special applications, it is possible to quote solutions in which the load current is fed direct to the relay coil, which enables the correct functioning of the load to be monitored. H-464 safety relays conform to DIN EN 61810-3 standard, Application type A, and IEC EN 61810-1. In addition, these safety relays also meet the requirements for railway signal relays in accordance with UIC 736e.
