Input: 2 * 4-20mA
Output: 4-20mA = average of 2 inputs.
If one input drops below 4mA, then the output is the other input only.
User Adjustments
- All measurements are normalised to 0-100%.
- The relays may be configured to operate off CH1, CH2 or M4.
- Calibration of CH1, CH2 and the 4-20mA output are accessible using the AM702 in trim mode.

| b | (uap1120b.usc = USC701 application program.)
(uap1120b.pdf = printable copy of this application.) Issue 'a' used the state of RLY1 and RLY2 to determine if the input has dropped below 4mA. Issue 'b' checks when the signal drops below 0% to determine if the input has dropped below 4mA. |
