In the FBs the output values are not limited to 0 … 1023, so the whole range of the
module can be used.
For voltages > 10 V or currents > 20 mA, values >1023 may be output, and for
voltages < 0 V or
< –10 V, negative values may be output. (With the W615 it is not possible to out-
put negative currents).
This extended range does depend on the tolerances of the components, and can-
not be guaranteed.
Connection concept for voltage and current outputs
The voltage and current output signals are connected directly to the 14-pole termi-
nal block (A0 … A5 / A3 and -).
The following connection diagram shows a typical wiring layout for:
● voltage outputs with the PCD2.W605 and .W625 modules or
● current outputs for the PCD2.W615 module
