4.2 Power Supply (Red, Brown)
The Brown wire is the Power Supply Common return, also named Ground. It
carries the return current for the power supply.
The Red wire is the Power Supply Input to the sensor. The sensor re9
- 36 VDC power and consumes 1.5 – 2 Watts of power (< 250mA draw)
depending on the sensor’s configuration.
Power supplies from 9 VDC to 36 VDC may be used. Higher voltages will
result in excessive current drawn by the over-voltage protection circuitry and
may cause permanent damage. Voltages less than 9 VDC may result in
inaccurate measurement readings or non-functionality.
4.3 RS232 / RS485 Serial Comm. (Green, Yellow)
Your sensor is configured with either RS232 or RS485 communications
