For those developing a product with signal relays according to the requirements of EN 50578
Over the last 35 years, numerous railway projects have successfully implemented Hengstler safety relays according to EN 50578. The range of applications include door controls, dead man's switches, point controls, axle counters and many more.
Extreme durability over 10M mechanical switching cycles
Extreme durability over 100k electrical switching cycles [with VA max.].
High shock resistance, normally open contact [g]: 10
High vibration resistance, normally open [g]: 10
Contact set according to requirements selection: 4, 5, 6, 7, 8 and 10
For those confronted with the choice of using safety relays vs. semiconductor technology.
When using safety relays with forcibly guided contacts, simple, robust and deterministic safety circuits are easier to implement. The diagnostic coverage is typically higher when using safety relays than with semiconductors.
Further advantages of safety relays over semiconductor technology
Contact sets and coil galvanically isolated from each other
Due to their design, contacts that are normally closed and normally open cannot be closed at the same time over the entire service life
High switching capacity without heat sink due to low contact resistances
Low power loss in the end product, which results in less temperature heating [∆T in K]
Very robust against EMV influences
Insensitive to voltage peaks
