Unified contactless advanced code track transmitter BKPT-UM

A unified contactless advanced code track transmitter is designed to generate digital code (pulse) combinations of ALSN and digital code interlocking signals, and monitor transmitter relays of track circuits far ends. The transmitter is used as a substitution of KPTSH-515 and KPTSH-715 transmitters.

Fields of application

The transmitter is designed for use in the existing digital code interlocking systems instead of KPTSH-515 or KPTSH-715 electromechanical code transmitters. The transmitter is installed in station relay rooms or relay cabinets of signal facilities at crossings, or on electric interlocking relay racks.
