摘要
FIELD: railway transport. SUBSTANCE: device has controller, current-limiting resistor, contactor, current relay, inertial supply unit, two locking relays and isolation diode. Novelty is provision of second locking relay and isolation diode which make it possible to use relays with contacts and coils operating under different potentials and consequently, making unnecessary additional measures to provide required isolation. EFFECT: enlarged operating capabilities. 2 dwg
