ABB TZIDC Digital Positioner DESCRIPTION

The TZIDC is an electronically configurable positioner with communication capabilities designed for mounting to pneumatic linear or rotary actuators.

It features a small and compact design, a modular construction, and an excellent cost-performance ratio. 

Fully automatic determination of the control parameters and adaptation to the final control element yield considerable time savings and an optimal control behavior.

Features

"Fail-freeze" function

If the electrical power supply should fail, the positioner output 1 (and 2, if applicable) is closed and the pneumatic actuator stops ("freezes") the valve in the current position. If compressed air supply should fail, the positioner depressurizes the actuator.

"Fail-safe" function

If the electrical power supply fails, the positioner output 1 is depressurized, and the pneumatic actuator’s return spring moves the valve to the defined safe position. In case of a double-acting actuator the second output 2 is additionally pressurized.
