ABB V18345-1027120001 TZIDC Positioner Architecture
The V18345-1027120001 intelligent electro-pneumatic positioner, engineered under the ABB TZIDC series, provides high-precision valve control for industrial process automation. Housed in a varnished aluminum enclosure, this single-acting fail-safe unit features an integrated local operator panel and indicator. It accepts a standard two-wire 4 to 20 mA input signal with HART communication support via an LCI adapter and FSK module, ensuring seamless integration into modern distributed control architectures.

Global PLC Spare HUB's Insight and Field Engineering Experience
During hazardous area commissioning of ABB TZIDC positioners, our instrumentation engineering team frequently encounters communication drops caused by improper grounding of the HART shield drain wire. When terminating the 4 to 20 mA loop inside high-vibration compressor skids, failing to use insulated wire end sleeves on fine-stranded AWG16 cables can lead to stray strand short-circuits across adjacent screw terminals.
Another critical field observation involves pneumatic port sealing: always apply PTFE thread sealant tape strictly to NPT threads while keeping sealant compounds away from the ¼-18 NPT internal nozzle ports. Blocked pneumatic pilots prevent the internal I/P converter from balancing nozzle backpressure, triggering immediate positioning error flags on the local operator display.
Target Equipment and Industrial Application Scenarios
- Linear Control Valves: Regulates modulating globe and gate valves across chemical processing plants.
- Rotary Actuated Dampers: Controls quarter-turn butterfly and ball valves in power generation boiler feeds.
- Exhaust Gas Scrubbers: Operates modulating pneumatic actuators in explosive ATEX-rated refinery zones.
Advanced Diagnostic Capabilities and Safety Features
- Fail-Safe Action Diagnostics: Automatically exhausts pneumatic actuator pressure upon electrical loop failure to drive valves to a safe position.
- HART Diagnostic Monitoring: Continuously reports valve travel deviation, operating hours, and internal temperature status via digital protocol.
- Local Operator Panel: Provides instant push-button configuration, diagnostic error codes, and calibration verification directly on the unit housing.
Package Contents, Warranty, and Express Logistics

Strategic Selection and Purchasing Guide
- Verify Enclosure Rating: Ensure the aluminum housing and ATEX Ex ia certification match your plant's hazardous area classification requirements.
- Match Actuator Action: Confirm that your control valve requires a single-acting fail-safe pneumatic configuration rather than double-acting control.
- Check Communication Needs: Validate that your control system architecture supports HART protocol over the 4 to 20 mA loop for remote asset management.
Frequently Asked Questions (FAQ)
Q: What is the primary function of the CF2 suffix on the V18345-1027120001 model?
A: The CF2 suffix indicates that the unit includes a Certificate of Compliance with the order in accordance with EN 10204-2.1 standards.
Q: How does the TZIDC positioner behave if the 4-20 mA control signal is abruptly lost?
A: Being a single-acting fail-safe unit, it automatically exhausts control air pressure to drive the valve safely to its predetermined home position.
Q: Can configuration parameters be modified without connecting an external HART communicator?
A: Yes, technicians can use the integrated local operator panel and indicator screen directly on the positioner housing for on-site setup.
Q: What cable gland thread size is required for electrical wiring entries?
A: The housing features standard ½-14 NPT threaded conduit entries for secure electrical cable connection.
Q: Why is it recommended to use wire end sleeves on flexible control wires?
A: Using wire end sleeves prevents stray fine strands from shorting against adjacent terminals under high industrial vibration conditions.
