Hybrid relay K1 (PWM)
If the control difference is x
di
≤ h, the hybrid relay clocks.
If the control difference is x
di
> h, he hybrid relay remains
permanently closed.
If the control difference is x
di
< 0, the hybrid relay remains
open.
Control of an external SSR relay (PWM)
The external SSR relay is switched via a voltage signal from the
controller.
If the control difference is x
di
≤ h, the analogue output and
the SSR relay clocks.
If the control difference is x
di
> h, a 10V signal is sent to the
output and the SSR relay switches on.
If the control difference is x
di
< 0, a signal with 0/2V is sent to
the output and the SSR relay switches off.
Control of an external power contactor (PWM)
The external power contactor is switched via the controller's
safety relay.
If the control difference is x
di
≤ h, the safety relay clocks.
If the control difference is x
di
> h, he safety relay remains
permanently closed.
If the control difference is x
di
< 0, he safety relay remains
open.
