Process Control System

Controller 170696
1/2
Design
The controller is mounted in a housing and installed in the controle console.
Function
The universal digital controller is suitable for use in individual closed control loops right
through to automation in process technology. Self-optimisation is built-in as standards
and operates according to FUZZY algorithms.
The configuration is effected via software and is equipped with a two-line alphanumerical
LCD display. The configuration and parameter settings are saved via a non-volatile
memory.
Note
Please follow the recommendations in the operating instructions.
