Introduction
IV. 4-20 mA ANALOG OUTPUT
The 4 to 20 mA analog output signal is relative to the Thermal Signal displayed on the Thermal Signal Bar Graph.
The 0% to 100% of Thermal Signal corresponds to 4-20 mA or 20-4 mA. Refer to View or Adjust the 4-20 mA
Output for programming this option.
• The 4-20 mA output signal corresponds to the scaled Thermal Signal view as determined by the range
(LED-0 and LED-100 pointers).
• The 4-20 mA signal may be displayed either as forward-acting (ascending 4-20 mA) or reverse-acting
(descending 20-4 mA).
• To view or adjust the 4-20 mA output current configuration: (refer to the Section 3, “View or Adjust
the 4-20 mA Output Configuration (Forward or Reverse)” or the “Classic 800 Series Quick Setup
Guide”
