ABB V18347 Tzidc-120 Foundation Fieldbus Communication Digital Valve Positioner
Product Description
V18347| TZIDC Electro-Pneumatic Positioner | ABBb
The ABB V18347 (model TZIDC - 120) is an electronically configurable positioner designed for mounting on pneumatic linear or rotary actuators. It features a compact design and modular construction, offering an excellent cost-performance ratio. With a microprocessor control, it can automatically determine and adapt control parameters to the final control element, achieving optimal control behavior and saving commissioning time. An I/P module with a pneumatic amplifier is used to control the pneumatic actuator, proportionally converting the electrical signal from the CPU into a pneumatic signal to adjust a 3/3-way valve, and continuously adjusting the air flow for the actuator. It has four pneumatic versions for single-acting or double-acting actuators, each with "fail-safe" or "fail-freeze" functions.
The TZIDC-120 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.

Advantages
Time Savings:
Auto-tuning function eliminates manual parameter adjustment, reducing commissioning time by up to 70%.
Remote configuration via Fieldbus minimizes on-site visits.
Enhanced Process Control:
Adaptive control algorithms optimize valve response, reducing process variability.
Fail-safe modes (open/close/freeze) ensure safety during power loss or signal failure.
Cost Efficiency:
Low air consumption reduces operational costs.
Long service life and minimal maintenance requirements lower total cost of ownership.
Safety & Compliance:
Certified for hazardous areas (ATEX, IECEx).SIL 2/3 capable (when configured with safety systems).
Diagnostic Capabilities:
Real-time valve health monitoring (wear, leaks, friction).
FDT/DTM compatibility for remote troubleshooting.
