Supplement 3 Unamplified function outputs
AUX3 … AUX6:
As in case the unamplified function outputs A
UX3 … AUX6 (logic level 0 V - 5 V, max. 20 mA) cannot switch greater
loads, switching amplifiers (MOSFET, bipolar transistors or the like) must be provided for consumers, which either
require a higher supply voltage (> 5 V) or a higher current (> 20 mA).
Supplement 4 Electric couplings / Freewheeling diode
Electric couplings - that is couplings, which can automatically uncouple remotely - are magnetic articles and therefore
inductive consumers.
When switiching off the current they may generate by the coil of the magnetic product a high voltage with opposite
polarity (up to several hundred volts) by self-induction. By exceeding the maximum cut-off voltage of the function out-
puts of the most sensitive MOSFET-output drivers, they can be destroyed irreparably!
It is therefore imperative to close shortly these voltages by freewheeling diodes:
