Abstract
A device is adapted to be associated with a group of input or output channels, especially of a programmable automatic controller, to detect if the channels are subject to an open circuit and/or an overcurrent. To each channel are assigned two analog comparators connected to a processor logic circuit which connects one or the other comparator output to a control unit. Configurator logic activates or deactivates one or the other of the comparators and associated forcing devices and filters according to the operating mode selected.
