Features:
- ABB ordering code V18345-2010421001 identifies a TZIDC intelligent digital electropneumatic positioner with painted aluminum housing, mechanical position indication, 4–20 mA two-wire input and an LCI adapter connector.
- V18345-2010421001 uses the documented painted aluminum housing, standard linear or rotary actuator mounting, no explosion-protection approval, double-acting fail-safe pneumatic execution, NPT cable and air connections, and 4–20 mA analog position feedback specification and requires confirmation against the supplied item and installed ABB configuration.
- Use this execution only on the documented control valve whose actuator geometry, double-acting fail-safe behavior, air supply, 4–20 mA loop and feedback circuit match the decoded ABB order code.
V18345-2010421001 must be matched to the receiving equipment and project record. Preserve the valve tag, mounting kit, lever ratio, 1/2-14 NPT cable entry, 1/4-18 NPT air connections, grounding and loop polarity; confirm clean instrument air before applying pressure. Run the ABB autoadjust procedure, then verify travel direction, calibrated endpoints, command response, 4–20 mA analog feedback and the documented fail-safe action across the full stroke.
Before replacing V18345-2010421001, record the installed position, hardware revision, mounting or connector arrangement, paired assemblies and every applicable ABB service record. Compare the supplied unit with the original item and approved configuration, isolate all relevant energy sources, and follow the documented installation procedure. After installation, inspect every affected mechanical, electrical and communication interface and complete controlled functional checks before returning the equipment to service.
The V18345-2010421001 ABB TZIDC intelligent digital electropneumatic positioner is listed as Active / Available from OEM. Current revision, availability and supplied scope are confirmed in the written quotation.
ABB V18345-2010421001 documentation and reference links.
Important Notice: Every linked document must identify the listed model or its documented family. Confirm the complete order code, hardware revision and installed-system requirements before replacement.
The complete V18345-2010421001 code defines housing, communication, approval, pneumatic action, connections, feedback and design; no segment may be substituted without review.
Match the NAMUR or VDI/VDE mounting kit, lever geometry, actuator stroke, clean instrument-air supply and NPT connections to the receiving valve.
Wire the two-wire 4–20 mA feedback separately from the control input, run autoadjust and verify command, actual position and fail-safe behavior.
