4.5. Sensor Wiring (J3)
Connect the sensor wires (for on-board, remote or stand-alone) to the
appropriate wiring terminals as follows. Refer to Figure 4-2 and Figure 4-5.
24 V: Red wire from sensor head (Red wire on BBIR)
485B: Yellow wire from sensor head (White wire on BBIR)
485A: Black wire from sensor head (Green wire on BBIR)
GND: Green wire from sensor head (Black wire on BBIR)
NOTE: Shielding from either the controller or remote sensors should be bonded
to the enclosure screw located inside the .
NOTE: The 24 V terminal supplies 24 VDC to the sensor for power. This
terminal should not be connected to the output of a 24 VDC power supply.

NOTE: For dual-sensor configurations, place both of the same colored wires in
the appropriate terminal block and firmly tighten.
NOTE: Use #18 AWG shielded cable for remote sensors. Maximum distance is
200 meters (BBIR maximum distance is 300 feet with #18 AWG wire).
NOTE: When wiring remote sensors to the , “485 B” on J3 should be
connected to “B-” in the remote sensor enclosure, and “485 A” on J3 should be
connected to “A+” in the remote sensor enclosure.
