37 Pulse width module XN-322-2PWM
The XN-322-2PWM module features two outputs (P1 and P2) on terminal X1
for pulse width modulation (PWM) that can be used to switch +24 V with an
adjustable frequency in order to drive inductive loads such as solenoid
valves, proportional valves, etc.
The two PWM outputs are powered via terminal X1 with a 24 V supply
voltage and 0 V. The supply voltage is monitored for undervoltage.
The XN-322-2PWM module can be configured with two parameters. The
pulse width is used to specify the length of the pulse duration within a period
and can be adjusted in increments of 0.5 s with software.
Meanwhile, the PWM frequency can be adjusted as a period in increments
of 0.5 s between 30.5 Hz and 20 kHz – please refer to  Section “Figure
172: Signal Pulse width modulation”, page 308
