Due to the direct connection to the output, the demagnetizing varistor is also effective at the
input. This is why the difference between UPx and the input signal must not exceed the clamp
voltage of the varistor. The varistor limits the clamp voltage to approx. 36 V. Consequently, the
input voltage must range from -12 V to +30 V when UPx = 24 V and from -6 V to +30 V when
UPx = 30 V.

The following drawing shows the circuitry of a digital input/output with the varistors for demag-
