Unit of speed control device BUKS-08

Block of speed control device BUKS-08 (hereinafter, the product) is designed to measure the actual duration of the signal from the rail circuit during the movement of passenger or household trains, for counting the current daily time and switching day and night modes of operation. The BUKS-08 product is a part of the speed control device. The product is designed for operation in relay rooms on relay stations. In terms of resistance to climatic factors during operation the product corresponds to classification group K1 according to OST 32.7-78, but for operation at extreme temperatures from 0 to +45 C0. Supply voltage is constant, positive within the range from +20 to +30 V, short-term increase of supply voltage up to 60 V is allowed. The power consumption of BUKS-08 on the power supply circuit is not more than 2 W. Input signal - closing of external relay contacts. The supply voltage in the input signal circuit is 15 V +/- 10 %, coming from BUKS-08. Consumption current on the input signalling circuit...
