Wiring
Use 12 AWG wire maximum for wiring terminals and copper or stainless steel
tubing for transducer connections. See Figures 5 to 8 for wiring diagrams and
Figures 9 and 10 for jumper designations.
Wiring for mA Output
The mA output pressure transducer must be powered with a 12 - 40 VDC power
supply. See Figure 3.

excessive moisture, or corrosive fumes are present. NEMA 4 housings are
primarily intended for outdoor use to provide a degree of protection against
windblown dust, rain, and hose-directed water.
Choose a vertical mounting surface for the pressure transducer.
Orient the pressure transducer so that the 1/8-inch NPT connection points
downward. See Figure 1.
Remove the transducer cover using a Phillips screwdriver.
Mount the pressure transducer using two #8 self-tapping screws (not
provided).
Pull the wires through the bottom of the enclosure and make the necessary
connections.
Replace the transducer cover and make the pneumatic connections.
Remove the blue terminal block by carefully pulling it off the circuit board.
Locate the [+] and [-] terminal markings on the board.
Attach the supply voltage to the [+] lead.
Connect the 4 - 20 mA output [[-] terminal) to the controller's input terminal.
Ensure that the power supply common is attached to the common bus of the
controller.
Reinsert the terminal block to the circuit board and apply power to the
transducer.
Check for the appropriate output signal by using a DVM set to DC milliamps
connected in series to the [-] terminal.

Remove the blue terminal block by carefully pulling it off the circuit board.
Locate the [+], [-], and [0] terminal markings on the board.
Attach the power wires to the [+] and [-] terminals. The [-] terminal is also the
negative output terminal.
Connect the [0] terminal, which is the positive VDC output terminal, to the
controller's input terminal.
Reinsert the terminal block to the circuit board and apply power to the
transducer.
Check the appropriate VDC output by using a DVM set to DC volts connected
to the [0] and [-] terminals.
