M-3160-003-1 05/12/2017
Output Operation:
Current or Voltage 0-20mA, 4-20mA, 0-5V, 0-10V Configuration:
This output will generate a current or voltage output reflecting the full scale of the sensor. This output is
factory set and calibrated to the user’s specified requirements at point of purchase.
If an output type was not specified by the user at time of purchase the default setup is set and calibrated
to 4-20mA. This is user adjustable out in field but will not be as accurate to what it was originally
calibrated to from factory.
The 4-20ma will drive into a maximum of 680Ω load impedance (line and input impedance) at 24V.
Be cautious when handling the GDA 3160 as there are delicate components that can easily be damaged
by static discharge. Always observe anti static precautions.
To change the output option:
1. Isolate the GDA 3160 by removing the incoming power source connector (P1) from the rear of the
board
2. Adjust jumper pins to the desired output configuration (see Table below)
3. Ensure output is configured for the changed output option
4. Revert to normal operation
