Supervised input: Sabotage detection
The supervised input is applicable in both usually open contacts and usually closed
ones. It consists of sabotage detection in the external device line. This detection can
be especially important in presence or alarm detection devices. A possible sabotage
would be a bypass in the cable (with usually closed contacts) or a cut in it (with
usually open contacts).
For line supervision, it is necessary for the external device to have serial termination
resistance of 1K (for usually closed contacts) or in parallel (for usually open contacts).
1K is the recommended resistance value, although it can vary slightly without
affecting the functionality.
Voltage supply
If the input is not passive, as it has been until now, an optical insulation between the
external device and our circuit is recommended (this insulation is especially useful in
order to avoid problems of potential differences between grounds). This is applicable
for both input with power and voltage supply. When a voltage supply is connected,
the device is able to detect the presence of voltages ranging from 3 to 30 V. As the
device idle status is initially unknown, activation is chosen when the source (V<2V)
