Wiring
• Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent electrical shock or equipment
damage.
• Use 14-22 AWG shielded wiring for all connections and do not locate the device wires in the same conduit with wiring used
to supply inductive loads such as motors. Make all connections in accordance with national and local codes.
• Pull at least six inches of wire into the enclosure, then complete the wiring connection according to the wire diagram for the
applicable power supply and output signal type.
• Select desired signal output type (mA or Vdc) by placing the output switch in required position, as shown in Figure 5.
Factory default is mA (4-20 mA).
• If mA was selected, no further Output set up is required. If VOLT output is selected in Figure 5, place Voltage Output Jumper
to desired span position, as shown in Figure 6. ie: 10 = 0-10 Vdc. Factory default is 10v = 0-10Vdc.
• Connect the DC positive or the AC voltage hot side to the PWR terminal. For voltage output or AC power, the supply
Common is connected to the COM terminal. The device is reverse voltage protected and will not operate if connected
backwards. It has a half-wave power supply so the supply Common is the same as the signal Common. See Figure 7.
•The analog output is available on the OUT terminal. Check the controller Analog Input to determine the proper
connection before applying power as shown in Figure 7.
• If installed, the resistance temperature output is available on the two terminals labelled TEMPERATURE SENSORas shown in
See Figure 8.
