4-Analog Output Module
Function
This digital module delivers 1 to 4
discrete opto-isolated analog outputs
deactivated. Several detectors can be
assigned to one output allowing the
management of the lowest, highest
and averaged value. When non
configured, the analog output is set to
0mA. The module also features two
logic inputs.
