Functional safety – RIDERSERIES FG

Weidmüller has expanded the RIDERSERIES to include

a relay variant with forcibly guided contacts. Relays with

forcibly guided contacts have a 99 % diagnostics coverage

and an excellent reputation for use in safety systems.

The contacts interlock mechanically with each other in order

to ensure a synchronous switching status of both contacts.

This guarantees that the alert contact will maintain the same

switching status in the event of an error (for example, if the

working contact welds from an overload). The controller

(or safety controller) detects the alert contact and then

compares the set values and actual values. If a difference

occurs, measures can then be taken to protect equipment

and human life.
