The 12V (pin7) can be used as the supply voltage to the sensor. Optionally, an external power supply
can be connected to the sensors if a different input voltage to the sensor is required.
For an example of sensor connection, refer to

Connect a current source sensor to either I+ or I-, depending on its operating range:
For positive current:
I+ (pin 5) - connect to the current output (Iout) of the sensor
I- (pin 4) - connect to ground.
GND (pin 6) - connect to the ground connection terminal of the sensor
The 12V (pin7) can be used as the supply voltage to the sensor. Optionally, an external power
supply can be connected to the sensors if a different input voltage to the sensor is required.

For negative current:
I - (pin 4) - connect to the current output (Iout) of the sensor
I+ (pin 5) - connect to ground.
GND (pin 6) - connect to the ground connection terminal of the sensor
