Switching, control and regulating device, for electrical heating of railway switching points, has all components mounted on base for providing module with bus interface

摘要

The device has at least one electronic setting element (2) for each points heating, an electronic device (3) with a microprocessor for controlling and regulating the heating, sensors (7) for detecting line currents, difference currents and the voltage, a control and regulation device, a protection device (5,6) and an operating and signaling plane, all mounted on a base (1) for providing a module with a bus interface. The base can act as a heat sink and can be fitted directly to a collector rail system.
