4 Electronic to Pneumatic Transducer
Publication 1414-IN006A-EN-P - October 2005
The transducer is jumper selectable. The factory default setting is 2-wire,
loop powered 4 to 20 mA device requiring a 4 to 20 mA signal connected to
the INPUT and COM terminals. The unit may also be configured for 3-wire,
0 to 10V dc operation by carefully changing the location of the jumper.
Three-wire operation requires a 24 to 30V ac or DC supply connected to
PWR and COM terminals in addition to the 0 to 10V dc signal applied to the
INPUT terminal.
3. Connect the pneumatic lines to the unit, ensuring that the main air supply is
connected to the black tube and the branch line is connected to the clear
tube.
The main and branch lines are also labeled on the end of the valve with a
‘M’ and a ‘B’.
4. The device may be tested by applying the input ZERO signal (either 4 mA or
0V dc as applicable) and checking the output for a pressure of 3 psig (21
kPa) (1) .
Adjust the input for the SPAN signal, 20 mA and check the output for a
pressure of 15 psig (103 kPa). The device is factory calibrated for these
ranges and should not be readjusted in the field.
5. If the unit does not perform as indicated in step 4, then verify all applicable
electrical signals (4 mA, 20 mA; or 10V and the power supply) using a
multimeter.
Also verify that the input air supply is 20 to 30 psig (138 to 207 kPa) and that
the unit is properly mounted and that all wiring is per the wiring examples.
(1) Use the gauge for the Electronic to Pneumatic Transducer to measure pressure (catalog number 1414-CADZZZZFZZ).
