Electrical Connections
Caution: All electrical connections should be made in accordance with any relevant local or
national legislation, standards or codes of practice.
Prosense detectors can operate between 12 - 24 VDC. The connection socket located on main
board as given in Diagram 7 and details given in below table 2:
The detector designed to give 4 - 20 mA current output signal. It is also possible to get
voltage value via using an additional resistor. Below table 3 gives recommended resistor
specifications to get correct voltage output from detector depending of the power source
level:
Detector Power VDC
12 VDC – 24 VDC
12 VDC – 24 VDC
Please consider the cable length when performing installation in the field. The Prosense
detector requires a power supply between 12VDC and 24VDC. Make sure that a minimum 12
VDC supply available at the detector entrance and consider the voltage drop due to cable
resistance in case of long distance applications.
