Principle of operation
The TZIDC-200, TZIDC-210, TZIDC-220 is an electronically configurable positioner with communication capabilities designed for
mounting on pneumatic linear or rotary actuators.
Fully automatic determination of the control parameters and adaptation to the positioner allow for considerable time savings as well
as optimum control behavior.
