There are many input ports and output ports on one IO board card, IN this embodiment, the input port IO _ IN4 and the output port IO _ OUT4 are taken as examples, and the rest of the input ports and output ports are the same as those of the input port IO _ IN4 and output port IO _ OUT4, which are not described again.
Specifically, the cathode and the anode of a diode of the optocoupler IN4 are respectively connected with a 5V power supply, and the cathode of the diode is also connected to the input port; the emitting electrode of the triode of the optocoupler IN4 is grounded, and the collector is connected with an IO _ IN4 connected to a target instrument through an IO board card.
The 5V power supply is connected to the anode of the diode of the optocoupler IN4 through a resistor R9 and connected to the cathode of the diode of the optocoupler IN4 through a diode D6 and a resistor R11.
When the input level of the IN4 changes, for example, the IN4 inputs a high level, and at this time, the diode of the optocoupler IN4 is turned off. And the IN4 inputs low level, the diode of the optocoupler IN4 is lighted, and the diode D6 is also lighted. It is therefore known whether the IN4 input is high or low through the diode D6. Thus, isolation of IN4 and IO _ IN4 is achieved.
Specifically, the cathode and the anode of the diode terminal of the optical solid-state relay OUT4 are respectively connected to a VCC power supply, and the collector and the emitter of the triode of the optical solid-state relay OUT4 are connected to a load; the target instrument is connected with the base of a switch tube Q1 through an IO _ OUT4 of an IO board card, the emitter of Q1 is grounded, and the collector is connected with the cathode of the diode end of the optical solid-state relay OUT 4.
When the input level of IO _ OUT4 changes, for example, when IO _ OUT4 inputs a high level, Q1 is turned on, the diode of the opto-solid relay OUT4 is turned on, and the diode D2 is also turned on. And the IN4 inputs low level, the diode of the optocoupler IN4 is extinguished, and the diode D2 is also extinguished. Thus, observing diode D2 can know whether the IO _ OUT4 input is high or low. Thereby achieving isolation of the load from IO _ OUT 4.
The VCC power supply is connected to the anode of the diode terminal of the photo-solid state relay OUT4 through a resistor R2; the VCC power supply is connected to the cathode of the diode terminal of the opto-solid state relay OUT4 through a resistor R3 and a diode D2.
The protection filtering module comprises a diode D1, a linear voltage regulator tube U1, a filtering capacitor C1 and a filtering capacitor C2; the anode of the diode D1 is connected with an input power supply, and the cathode is grounded through filter capacitors C1 and C2 respectively; the input end of the linear voltage-stabilizing tube is connected with the cathode of the diode D1, and the output end of the linear voltage-stabilizing tube outputs the 5V power supply.
The IO board card based on the isolation of the optical solid-state relay OUT4 is mainly improved from a power supply and an input/output IO port. The input power supplies power to the target instrument or the all-in-one machine after the IO board card protection and filtering, and can be arranged comprehensively to prevent conducted interference when wiring. The input port is electrically isolated from the outside by TLP291 optocouplers IN 4. The delivery outlet is realized with outside electrical isolation with light solid state relay OUT4, keeps apart than conventional opto-coupler IN4 and relay, and light solid state relay OUT4 has that response speed is fast to transmit the time delay little, and two-way electrodeless output, contactless no rebound, and the area load capacity is strong, but the advantage of direct drive direct current and AC alternating current load, and the above-mentioned embodiment of function of reinforcing IO integrated circuit board greatly only is used for explaining the utility model discloses, and not be used as the restriction of the utility model.
