The invention provides a control signal output circuit which comprises a trigger SN74V1G14, a follower circuit, an amplifying circuit and a V/I circuit. The input end of the trigger is connected with the signal input end through a resistor R1, and the power end of the trigger is connected with the 2.5 V reference voltage. The follower circuit comprises an operational amplifier TLV 2372. The input end of the operational amplifier TLV 2372 is connected with the output end of the trigger through two RC circuits. The output end of the operational amplifier TLV 2372 is connected with the input end of the V/I circuit and the input end of the amplifying circuit through an RC circuit. The input end of the V/I circuit outputs 4 mA to 20 mA current signals. The output end of the amplifying circuit outputs 0V to 10 V voltage signals. According to the control signal output circuit, multiple stages of RC filtering are designed, a fuse protector is designed at the current signal output end, a clamping protection diode is designed at the voltage signal output end, the stability of the output voltage signals and output current signals is enhanced, and the safety of electronic components inside the circuit is guaranteed powerfully.
