An electronic PI temperature controller has an output p of 12 mA when the set point equals the nominal process temperature. The controller response to step change in the temperature set point of 2.5 mA (equivalent to a change of 5F) is shown below: t, s p, mA 0 8.0 0+ 6.7 20 6.0 60 4.7 80 4.0 Determine the controller gain Kc (mA/mA) and the integral time, I. Is the controller reverse-acting or direct-acting
