WIRING
•
Deactivate the 24 Vac/dc power supply until all connections are made to the device to prevent electrical shock or equipment damage.
•
Select desired signal output type by placin the output jumper in required position, as shown in Figure 5. Please note that pin connection
tabs in jumper must be in vertical position.
•
If voltage output is required, place Voltage Span Jumper to desired span position, as shown in Figure 6. I.E. 10 = 0-10 Vdc.
•
Connect the plus dc or ac voltage hot side to the POWER terminal. For voltage output or AC power, the supply common is connected to
the COMMON terminal. The device is reverse voltage protected and will not operate is 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 RH OUTPUT terminal. Check the controller Analog Input to determine the proper connection before
applying power. See Figure 7.
•
If installed, the resistance temperature signal is available on the two terminals labeled TEMPERATURE SENSOR. See Figure 8.
