Technical description

Important! The signal ground (GND) of the analogue interface and the negative (-) output are internally
connected. When wiring these two lines seperately to a control application (eg. a SPS) and a load, they must
not be connected directly to each other at the external application! Else the load current may be distributed
over both lines and damage the normally small-sized control lines.
This problem does not occur if a galvanic isolation of the control signals is used at any point, for instance
when using a CAN or GPIB interface card.
Correct Wrong
One possible solution is given below. In order to measure the voltage at the load, wire the „Remote sense" feature.
The actual value output UMON can be wired with the control application to measure the voltage.
