At the end of the (Timer) cycle time, the controller closes the
assigned timer relay for a period of

[Pulse length (PWM)]
If the output relays are configured as
these output relays emit the pulse length determined by the con‐
troller, to control an actuator (e.g. motor-driven metering pump, sol‐
enoid valve).
