2.9.3 Suppressor circuit for inductive loads
High induced voltages may be produced when inductive loads are switched
off.
In order to prevent system malfunctions caused by voltage peaks (e.g., cou-
pling on analog cables), it is recommended to use a suppressor circuit (RC
suppressors or flyback diodes) directly on inductive loads.
2.9.4 Connecting inputs
XControl features inputs with a +24 V level that can be used to read signal
states "0" and "1". The modules feature input filters designed to suppress
glitches on the corresponding signal cables.
Inputs I1 to I4 can be parameterized as interrupt inputs.
Connect the inputs with a shielded connection cable with a maximum length
of 30 m.
An LED is assigned to each input in order to indicate the input's current
state.
