Encoder working power

There are generally three types of operating power sources for encoders: 5V DC, 5-13Vdc or 11-26Vdc. If you buy an encoder with 11-26Vdc, you can use the 24V power supply of the PLC. It should be noted that:

There are generally three types of operating power sources for encoders: 5V DC, 5-13Vdc or 11-26Vdc. If you buy an encoder with 11-26Vdc, you can use the 24V power supply of the PLC. It should be noted that:

1. The current consumption of the encoder is within the power supply range of the PLC.

2. If the encoder is output in parallel, connected to the I/O point of the PLC, you need to know whether the signal level of the encoder is push-pull (or push-pull) output or open-collector output. If the encoder is output in open-set, there are two types, N-type and P-type, which should have the same I/O polarity as the PLC. If it is a push-pull output, there is no problem with the connection.

3. If the encoder is output from the driver, the general signal level is 5V. Be careful when connecting and do not let the 24V supply level string into the 5V signal line and damage the signal end of the encoder.

6. Many times it is not the encoder that is broken, but the interference, resulting in a bad wave pattern and inaccurate counting.
