The sound and light alarm circuit for industrial instrumentation is composed of the +12 V voltage-stabilizing circuit, switch control circuit, oscillator, bistable flip-flop, sound and light alarm circuit, and the circuit is shown as the chart. +12 V voltage-stabilizing circuit consists of resistors R2, R3, filter capacitors C1, C5, C6 and regulator diode VS. Switch control circuit consists of resistors R1, R12, optocoupler VLC and industrial instrumentation control contact (controlled electrical contact) Kx. Oscillator is composed of the D1, D2 which are inside of NOT gate IC IC (D1 ~ D5) and diode VD2, resistor R11, capacitors C2, C3. Bistable flip-flop is composed of the D3 ~ D5 which are inside of IC and resistor R7.
