TY155/GRP04

Description

D.C. NON-SAFETY TIME DELAY RELAY
The TY155/GRP04 is a 1F 3B non-safety 10 second time delay relay unit for use in point control circuits operating a point contactor relay to BR943. The contacts within this relay unit are rated to carry no more than 300 mA. It is used to disconnect the BR943 relay coil if the latter is not otherwise de-energised, within a predetermined time. The time delay provided is sufficient to allow the point machine to complete its normal operation. Of compact modular plug-in design it is equipped with a safety interlocking system (pin code) for insertion into mating plugboards.
