Analogue Channel Inputs - Prosense DPX Series User Manual

5.2 Analogue Channel Inputs:

DPX series Gas Control Panel has analogue channel inputs to connect detectors via using
4-20mA output. DPX4 Panel has 4 analogue channel inputs while DPX8 Panel will have 8
analogue channel inputs.
Panel must be connected to detectors through V+, V-(GND) and S via using three-wire cable.
Panel channels supply 24VDC power to detector and read the output signal of detector from
S port. Thus connections should be made correctly to do not cause any damage on the
detectors. Detector connections should be made with 3 core cable and pin definitions are as
follows:
A sample connection schema is shown in below figure:
