A method of connecting a rotary encoder to a PLC

NPN open collector output

Method 1: As shown below

Encoder|Transmitter|Encoder|Soft starter|Power supply|VFD|Light curtain|Servo products|Human-machine interface|Solenoid valve|Cylinder|Actuator|Flow meter|Transformer|Thyristor|Sensor|Deceleration drive gearbox reducer|Linear guide|Circuit breaker|Refrigeration compressorAll industrial products of okplazas are purchased from the original factory or formal channels of agents to ensure the original authenticity, which perfectly solves the problem of industrial product sample procurement and small-batch procurement for the majority of engineers and purchasing personnel.

This wiring method is used when the sensor's working voltage is different from the PLC's input voltage, take the encoder transistor part, and connect it to the power supply in series to connect to the PLC in a non-voltage form. But it should be noted that the voltage of the external power supply must be below DC30V, and the switching capacity is below 35mA per phase. If the working voltage is exceeded, the encoder may be damaged.

The specific wiring method is as follows: the brown wire of the encoder is connected to the positive electrode of the encoder working voltage, the blue wire is connected to the negative electrode of the encoder working voltage, the output wire is connected to the input point of the PLC in turn, the blue wire is connected to the negative electrode of the external power supply, and the positive electrode of the external power supply is connected to the PLC. Enter the com terminal.
