Abstract
The issue of developing a Microprocessor operate unit for single shunting traffic lights НМ1 discussed in the article. The schematic diagram of the block was analyzed and determined which elements, with which microelectronic devices, should be replaced. In a block containing 5 relay circuits, the rails are considered electric loops of the direction of movement of the currents in the working holate transition. The analysis of the operation of the block in the circuit of push-button relays that receive power from the HMID block, the calculation of the estimated current strength, showed the need to use a Pvg612 type optocoupler in this circuit.
