FAQ

Q1: What is the main function of the ABB V18345-1010221001 device?

A1: It is an electronically configurable positioner (TZIDC series) designed to accurately control pneumatic linear or rotary actuators.

Q2: How does it control the actuator?

A2: It uses a proven I/P converter and a 3/3-way valve to proportionally translate an electrical signal into precise pneumatic pressure for actuator movement.

Q3: What is a key setup benefit of this positioner?

A3: It features fully automatic determination of control parameters and adaptation to the final control element, saving commissioning time and optimizing performance.

Q4: What pneumatic actuator types is it compatible with?

A4: It is available in versions compatible with both single-acting and double-acting actuators.

Q5: What safety functions does it offer?

A5: It provides configurable "fail-safe" (moves to a predefined position) or "fail-freeze" (holds last position) safety functions upon failure.
