PID Control Typical

Norsok I-005 “CA” block is used to implement PID control. CA block can be connected directly to transmitter and valve.

When alarms (HH, LL) from transmitter are needed, additional upstream MA block should be used. MA block is intended for monitoring of analogue value and has AHH and ALL outputs (Alarm High High and Alarm Low Low).
