The imc CANSAS-DI16 module's inputs are organized in pairs which are isolated from other inputs. The
pairs' own reference grounds are not connected to the DI16 module's internal ground or CHASSIS.
Eight inputs are accessible per connection terminal.
Open inputs are set to LOW "0".
The board with the signal processor (DSP) is at internal ground potential GND. This is the module's
internal "digital ground", and is connected to the chassis as well as to the shielding of the input plug.
This internal electric potential must not "float" in relationship to the power supply or the CAN-bus.
Rather, the maximum voltage differential of 50 V to GND must not be exceeded, so GND must be held
at a suitable value. Otherwise, the module can sustain damage or malfunction. A chassis connection is
provided in the form of the shielding terminal.
An example for digital inputs: -IN7/8 is the shared ground connection for the inputs +IN7 and +IN8.
This ground is not connected to the chassis.
It is generally recommended to connect the housing (chassis) to ground (protective grounding line).
The housing mainly consists of conduction material.
The digital inputs are sampled at intervals of 0,1 ms, no matter what the specified samp-ling interval
is. But afterwards the data is reduced to fit the specified sampling interval.
