  • V18345 = TZIDC intelligent positioner
  • 1 = Aluminium case, IP65, linear/rotary mounting
  • 0 = No explosion protection
  • 1 = Single acting, fail safe
  • 2 = 1/2-14 NPT cable entry, 1/4-18 NPT air pipe
  • 0 = No analog position feedback module
  • 0 = No mechanical kit for digital feedback
  • 1 = Standard varnish/coding

Input Signal Specifications

• Signal type: 4 to 20 mA (two-wire technology)
• Minimum signal: 4 mA
• Maximum signal: 20 mA (0 to 100% position)
• Split range operation: freely selectable
• Minimum span: 20% (3.2 mA)
• Recommended span: >50% (8.0 mA)
• Action: increasing 4-20mA = 0-100% position
• Action: increasing 20-4mA = 0-100% position

Characteristic Curves

• Linear characteristic
• Equal percentage 1:25 or 1:50
• Equal percentage 25:1 or 50:1
• Freely configurable with 20 reference points

Digital Input

• Control voltage: 0 to 5 V DC = logical 0
• Control voltage: 11 to 30 V DC = logical 1

Digital Output (NAMUR)

• Follows DIN 19234 / NAMUR standard
• Supply voltage: 5 to 11 V DC

Pneumatic Data

• Supply pressure: 1.4 to 6 bar (20 to 90 psi)
• Air consumption: < 0.03 kg/h (0.015 scfm)
• Air consumption does not change with supply pressure.
• Pneumatic connections: G 1/4 or 1/4-18 NPT

Travel and Shut-Off Functions

• Travel limit: reducible within full 0-100% range
• Minimum travel: 20% of full range
• Shut-off function: settable for each end position
• Shut-off causes immediate travel to set end position.
• When shut-off value = 0, position stays controlled even at end.
• Travel time prolongation: increase max travel time per direction.

• With proximity switch SJ2-S1N: -25 to 85°C
• Operational humidity (closed housing, air on): 95% annual avg
• Condensation is allowed during operation.
• Transport/storage humidity: 75% annual avg, non-condensing

Housing and Connections

• Housing material: Aluminium
• Protection class: IP65 / NEMA 4X
• Surface: electrostatic dipping varnish, epoxy resin, stove-hardened
• Case color: black RAL 9005 matte
• Cover color: Pantone 420
• Electrical terminals: screw type, max 2.5 mm2 for analog signal
• Do not put strain on terminals.
• Cable entry: 2 tap holes 1/2-14 NPT

Installation Guide

• Mount positioner on linear or rotary actuator.
• Use 1/2-14 NPT cable gland for electrical wiring.
• Connect air supply to G 1/4 or 1/4-18 NPT port.
• Wire 4-20mA input to two-wire loop.
• Keep housing closed to maintain IP65 rating.
• Set fail safe mode during commissioning.

Debugging and Maintenance

• Check input current between 4 and 20 mA.
• Use operator panel to view position feedback.

• Shut-off function protects valve seats.
• Travel time prolongation for slow movement.
• Split range operation for two actuators on one signal.

Frequently Asked Questions

• What is fail safe mode?
  • On power loss, actuator moves to safe position.
  • This prevents damage or unsafe conditions.
• Can I use this positioner without position feedback module?
  • Yes, this model has no feedback option (option 0).
  • Use operator panel for local position reading.
• Positioner does not move actuator.
  • Check supply pressure between 1.4 and 6 bar.
  • Verify input current is above 4 mA.
  • Look at operator panel for error codes.
• What is the minimum travel range?
  • Minimum travel is 20% of full range.
  • You can reduce travel within 0-100%.
• Purchase Guide (Selection Guide)
  • Choose V18345-1010120001 for single acting fail safe.
  • Pick this model when no position feedback is needed.
  • Select for non-hazardous areas (no explosion protection).
  • Use with linear or rotary actuators.
  • Verify air supply pressure and thread type.
  • For analog feedback, choose model ending with different option.
