Eaton’s FHF TAR 22 is a telephone connecting relay which is designed specifically for application in rough and harsh conditions in industrial areas. 

The TAR 22 provides potential-free switching contacts for connection of signalling devices, this enables devices such as a horn or flashing light to be switched on by the ringing signal. The ringing break bypass can be custom configured.

This telephone connecting relay is used for ringing signalling purposes when a normal alert signal is not sufficient. The TAR 22 housing is manufactured from glass-reinforced polyester providing durability and longevity, with the enclosure forming a protection degree of IP66.
