4.4 Power and Output Wiring (J1)
Connect the power and signal wires to the appropriate wiring terminals as follows.
• 24 V:Connect 24 VDC (12-28 VDC) supply power
• CH 1:Channel 1, 4-20 mA output signal
• CH 2:Channel 2, 4-20 mA output signal
• GND:DC return
Figure 4-2 Power and Signal Connector J1 on the
NOTE: Use supplied green conductor for enclosure ground. Public 485 GND is to be used for
ModBus digital ground.
NOTE: The is a 3- or 4-wire 4-20 mA device. For dual sensor configuration you must
have a second 4-20 mA signal wire pulled to the unit.
NOTE: When not using 4-20 mA outputs, use the supplied resistors to connect CH-1 and CH-2
to GND. If these resistors are not connected and the 4-20 mA outputs are not used, a “P” will
appear on the display, indicating an open loop condition.
4.5 Sensor Wiring (J3)
Connect the sensor wires (for on-board, remote or stand-alone) to the appropriate wiring
terminals as follows.
• 24 V:Red wire from sensor head
• 485A:Yellow wire from sensor head
• 485B:Black wire from sensor head
• GND:Green wire from sensor head
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.
