4000 Series MMT and MPT Firmware New Feature

The following feature has been added to the 4000 Series firmware 1.40:

  • Ability to configure the analog output of a 4000 series transmitter to track an input variable.

Some versions of the 4000 Series transmitters have a single 0-20mA current analog output. The analog output can configured as a PID controller or may be used as a general purpose analog output.
A new feature has been added to the 4000 Series firmware version 1.40 that allows a user to configure the analog output of a 4000 Series transmitter (if equipped) to simply track one of the measured input variables. When configured to track an input variable, the value of the analog output is set proportionally to the value of the input variable.
