Connection of sensors with frequency outputs

The following figure shows exemplarily the electrical connection of sensors with frequency outputs to the input Z0 of the module CD522. Proceed with the A0, B0, A1, B1 and Z1 in the same way.

Connection of sensors with frequency outputs to the module CD522

Attention

:strong:Risk of malfunctions!

The edges of a signal must be strong enough (0.4 V/µs) to be recognized correctly by the CD522.

Put an 1 kΩ resistor between 0 V and the Z terminal when using a standard output as time generator.

The meaning of the LEDs is described in the Displays Encoder & PWM Module CD522.
