摘要
The circuit is intended for use with electronic overcurrent relays. It has a counter unit with a decoder and a multiplexer, to which in case of overload a number of pulses proportional to the time lag is applied. a luminous digital display unit follows the counter. The counter is connected through a high resistance resistor to a power supply unit, and in parallel with a capacitor. The luminous display unit is connected through a key to a power supply unit terminal.
