Fig. 6: Type 3433 Controller Modules
Type 3433-2 PI Controller Module
The following controller module versions are
almost identical to the Type 3433-2 PI Con
-
troller Module, except they are fitted with, for
example an operating point adjuster, a de
-
rivative element or a selector switch, de -
pending on the application.
Type 3433-1 P Controller Module
This module is largely identical to the
Type 3433-2, except an operating point ad
-
juster is used instead of the integral element.
Type 3433-3 PID Controller Module
This module is largely identical to the
Type 3433-2. However, it contains an addi
-
tional derivative element providing a deriva -
tive-action gain of approx. ten times in the
input branch of the controlled variable x. The
derivative-action time can be adjusted at the
Tv restrictor.
