PWM signal mode

Notice

Feedback at the 24 V outputs

A voltage of 24 V at outputs 3 and 4 can destroy the device (feedback). No voltage may be applied to the outputs in PWM mode.

The PWM signal mode enables a pulse width modulated binary signal to be output at outputs 3 and 4.

PWM signal mode 1:
Configurable inputs and outputs in PWM signal mode

This signal is separated into duty cycle (0... 100 %) and PWM clock frequency (15 Hz... 100 kHz). The LEDs are clocked with the outputs, and show the duty cycle by their brightness. The signal values are transferred in 16-bit values.
