      Overview Manuals Common Applications Product Precautions
      V18345-2010421001 provides intelligent closed-loop valve positioning from a 4-20 mA controller setpoint while returning a separate 4-20 mA analog position-feedback signal.
      • Converts a 4-20 mA two-wire setpoint into controlled pneumatic actuator movement
      • Supports linear and rotary actuator mounting with a mechanical position indicator
      • Provides double-acting fail-safe output behavior when electrical power is lost
      • Returns actuator position through a separate 4-20 mA two-wire analog-feedback module

      The positioner is installed on a matched linear or rotary actuator and supplied with clean instrument air through the documented NPT connections. Commissioning confirms mounting geometry, signal polarity, pneumatic routing, analog feedback, operating direction, travel limits and double-acting fail-safe response.

      Important Notice: Confirm V18345-2010421001, TZIDC hardware execution, actuator type and mounting standard, mechanical position indicator, 4-20 mA input and feedback loops, double-acting fail-safe pneumatic configuration, 1/2-14 NPT cable entry, 1/4-18 NPT air connections, supply pressure, grounding, Auto Adjust result and controlled stroke-test evidence before commissioning.

      The first document is the model-specific technical and system reference. The second is a distinct field workbook for installation, wiring, commissioning and acceptance records.

      Linear control-valve positioning
      Positions a NAMUR-mounted linear actuator from the documented process-control setpoint.
      Rotary actuator modulation
      Controls a VDI/VDE 3845 rotary actuator with configured travel and direction.
      Double-acting fail-safe service
      Applies the documented pneumatic safe-position behavior when electrical power is removed.
      Valve position feedback integration
      Returns the installed actuator position to the control system through the separate analog-feedback loop.
      Read the applicable ABB installation instructions before work. Verify V18345-2010421001, the installed host system and all configured field interfaces before isolation, wiring or commissioning.
      1
      Confirm the full V18345-2010421001 order code, TZIDC nameplate and installed actuator duty.
      2
      Place the valve, process and associated control loop in the approved maintenance state.
      3
      Isolate the 4-20 mA circuits and instrument-air supply before disconnecting the positioner.
      4
      Record signal polarity, feedback wiring, NPT cable entry and both pneumatic port assignments.
      5
      Inspect the mounting bracket, feedback linkage, shaft alignment, tubing and protective grounding.
      6
      Restore the documented travel direction, limits, analog-feedback setup and standard Auto Adjust sequence.
      7
      Review the LCD status, setpoint, actual position, control deviation and stored diagnostic messages.
      8
      Stroke the actuator under controlled conditions and prove signal tracking, feedback and fail-safe response before release.

      Technical notes

      Mount V18345-2010421001 on the documented linear actuator in accordance with DIN/IEC 534/NAMUR or on the documented rotary actuator in accordance with VDI/VDE 3845. Preserve the 4-20 mA polarity, LCI connection, 1/2-14 NPT cable entry, 1/4-18 NPT pneumatic ports and analog-feedback loop, then run ABB Auto Adjust and verify controlled fail-safe behavior.

      FAQS

      • How should the complete V18345-2010421001 identity be verified before installation?
        Confirm V18345-2010421001, TZIDC hardware execution, actuator type and mounting standard, mechanical position indicator, 4-20 mA input and feedback loops, double-acting fail-safe pneumatic configuration, 1/2-14 NPT cable entry, 1/4-18 NPT air connections, supply pressure, grounding, Auto Adjust result and controlled stroke-test evidence before commissioning.

Commissioning confirms mounting geometry, signal polarity, pneumatic routing, analog feedback, operating direction, travel limits and double-acting fail-safe response.
      • What wiring and connector evidence should be retained before removing V18345-2010421001?
        Isolate the 4-20 mA circuits and instrument-air supply before disconnecting the positioner. Record signal polarity, feedback wiring, NPT cable entry and both pneumatic port assignments.
      • What configuration must be restored after fitting V18345-2010421001?
        Restore the documented travel direction, limits, analog-feedback setup and standard Auto Adjust sequence.
      • Which diagnostics should be reviewed after powering V18345-2010421001?
        Review the LCD status, setpoint, actual position, control deviation and stored diagnostic messages.
      • What controlled test is required before V18345-2010421001 returns to service?
        Stroke the actuator under controlled conditions and prove signal tracking, feedback and fail-safe response before release.
      • Which official document supports the published data for V18345-2010421001?
