Fixed setpoint controller with S-output, internal feedback.
controlled variable via four-wire transmitter
position feedback y
The controlled variable x from a four--wire transmitter goes to
the analog input AE1, signal range 4 to 20 mA.
The manipulated variable is switched from the digital outputs via
external coupling relays to the actuating drive.
4 to 20 mA are available ar AE2 as a position feedback (only for
display on the controller)(position feedback potentiometer with
two-wire connection).
The actuating drive has a runtime of 60 s (for 0 to 100 %
deviation).
