ABB V18345-1010221001 | TZID-C Smart Positioner – 4-20 mA

Description Product Introduction The ABB V18345-1010221001 is a TZID-C digital valve positioner—the industry standard for precise control of pneumatic actuated valves. This positioner takes a 4-20 mA command signal from a PLC or DCS, compares it to the actual valve position feedback, and adjusts the pneumatic output to drive the valve to the setpoint. It’s used on control valves in refineries, chemical plants, power generation, and water treatment. What makes the ABB V18345 the go-to positioner for critical applications is the combination of robust construction and advanced diagnostics. The “1010221001” suffix breaks down as follows: 10 = single-acting (spring-return) actuator, 10 = 4-20 mA input with HART, 221 = standard mechanical limit switches, 001 = standard housing. In my experience, the TZID-C is one of the easiest positioners to commission. The auto-calibration routine runs in under 90 seconds and works with virtually any pneumatic actuator. The “C” in TZID-C stands for “compact”—this version uses a smaller housing than the original TZID, making it easier to fit in tight actuator mounting configurations.   Key Technical Specifications Parameter Specification Model ABB V18345-1010221001 Series TZID-C Input Signal 4-20 mA (analog) Communication HART (digital over 4-20 mA loop) Actuator Type Single-acting (spring-return) Supply Pressure 1.4–7 bar (20–100 psi) Output Pressure 0–100% of supply Flow Capacity 110 l/min at 6 bar (air) Stroke Range 5–130 mm (linear) or 0–90° (rotary) Accuracy ±0.5% of span Hysteresis < 0.3% Repeatability < 0.2% Protection Class IP66 (NEMA 4X) Operating Temp -40°C to 85°C Materials Aluminum housing, stainless steel internals Approvals ATEX, IECEx, CSA, FM (intrinsically safe)   Firmware / Software Versions & Upgrade Notes The ABB V18345-1010221001 contains firmware that is not field-upgradable. The positioner’s behavior is determined by its hardware revision and configuration parameters. Software compatibility: The positioner can be configured with the local display, a HART communicator (like an Emerson 475), or ABB’s TZID-C software via a HART modem. Configuration storage: All configuration parameters are stored in non-volatile memory in the positioner. No battery backup required. Firmware note: The V18345 uses a fixed firmware version based on manufacturing date. Later revisions add features like extended diagnostics and support for newer HART commands. The “1010221001” suffix indicates a specific hardware configuration, not a firmware version. Field note: The ABB V18345 has a local display that shows valve position, input signal, and configuration menus. If the display is blank, check the 4-20 mA loop—the positioner is loop-powered and will not operate without at least 3.5 mA.   Compatibility & Replacement Matrix Original Model Replacement Model Compatibility Level Key Notes ABB TZID (original) ABB V18345-1010221001 Needs adaptation Original TZID had a larger housing. The TZID-C has different mounting footprint. Check actuator bracket compatibility. ABB V18345 (other suffixes) ABB V18345-1010221001 Drop-in (with function check) Same physical dimensions. Different suffixes indicate different options (double-acting, limit switches, etc.). ABB V18345-1010221001 (same) Drop-in Direct replacement. Any V18345 with same suffix is interchangeable. ABB V101 (older positioner) Needs full rework Different mounting, different pneumatic connections, different wiring. Not a direct swap. Third-party positioner (Fisher, Siemens) Needs adaptation Different mounting, different calibration procedures. Not a plug-and-play replacement.   Frequently Asked Questions Q: What does the “1010221001” suffix mean? The suffix breaks down as: 10: Single-acting actuator (spring-return) 10: 4-20 mA input with HART 221: Mechanical limit switches (2 x SPDT) 001: Standard housing, no explosion-proof certification The is the standard configuration for most industrial applications: single-acting actuator, analog control, and built-in limit switches for position feedback. Q: How do I commission this positioner? The ABB V18345 has an auto-calibration routine: Apply 4-20 mA signal (at least 3.5 mA to power the device) Use the local display buttons to enter the configuration menu Select “Auto-Adjust” The positioner will stroke the valve fully open and closed, measure the travel, and set PID parameters automatically The process takes about 90 seconds No PC or HART communicator is required for basic commissioning—the local display handles everything. Q: What supply pressure do I need? The requires clean, dry instrument air at 1.4–7 bar (20–100 psi). The output pressure to the actuator will be the supply pressure minus the internal drop. For most spring-return actuators, 3–4 bar is sufficient. The positioner has an internal pressure regulator and does not require external regulation. Q: My positioner shows “ERR 001.” What does that mean? Error 001 on the display indicates a communication error between the microprocessor and the analog input circuit. Common causes: 4-20 mA loop current below 3.5 mA Loose wiring Damaged analog input board Check the loop current with a multimeter. If it’s above 4 mA but the error persists, the positioner may need replacement. Q: Can I use this with a double-acting actuator? No. The is configured for single-acting (spring-return) actuators. For double-acting actuators, you need the -1020221001 (suffix starting with “10” is single-acting, “20” is double-acting). The hardware is different—single-acting units have one pneumatic output; double-acting have two. Q: Does this positioner support HART communication? Yes. The includes HART communication over the 4-20 mA loop. You can connect a HART communicator or use a HART modem to access diagnostics, configure parameters, and view valve performance data. The HART device address is configurable. Q: How do I wire the positioner? The has a terminal block inside the housing: Terminal 1: 4-20 mA input ( ) Terminal 2: 4-20 mA input (-) Terminals 3–6: Limit switch outputs (dry contacts) The positioner is loop-powered—no external power supply is needed. The 4-20 mA loop provides both power and the control signal. Minimum loop current for operation is 3.5 mA. Q: My valve position is oscillating. What should I adjust? Oscillation on the usually indicates too much gain. Enter the configuration menu and reduce the “Gain” parameter (often called “Kp”). The auto-calibration sets gain based on actuator size, but for small actuators or fast valves, manual reduction is sometimes needed. Also check the supply pressure—if it’s too low, the valve may not have enough force to hold position. Q: What’s the difference between TZID and TZID-C? The TZID-C (“C” for compact) uses a smaller housing, simplified wiring, and updated electronics compared to the original TZID. The is the TZID-C version. It has the same performance specifications but a 30% smaller footprint, making it easier to mount on smaller actuators. Q: How do I test the limit switches? The has two mechanical limit switches (SPDT) that can be set to trip at specific valve positions. Use the local display to enter the “Switch” configuration menu, set the positions (e.g., 0% and 100%), and manually stroke the valve to verify switch operation. The switch contacts are accessible on terminals 3–6.
