• Minimum current: 3.4 mA without analog feedback, 3.5 mA with analog feedback
• Start-up current: 3.8 mA
• Load voltage at 20 mA: 8.7 V DC without explosion protection, 9.7 V DC for intrinsically safe versions
• Impedance at 20 mA: 435 ohms standard, 485 ohms for intrinsically safe devices
• Digital input: 24 V DC control voltage (12…30 V DC), logical “0” at 0…10 V DC, logical “1” at 12…30 V DC
• Digital output: NAMUR DIN 19234 control circuit, 5…11 V DC supply, <1.0 mA for logical “0”, >2.0 mA for logical “1”
• Output range: 0…6 bar (0…90 psi)
• Air capacity at 1.4 bar (20 psi): 5.0 kg/h = 3.9 Nm³/h = 2.3 scfm

• Output function: Single acting, fail freeze; air vents from actuator or actuator blocks on electrical power failure
• Shut-off values: End position 0% = 0…45%, end position 100% = 55…100%
• Housing: Aluminium case, varnished, IP 65 (NEMA 4X)
• Mounting: Linear actuators per DIN/IEC 534 / NAMUR or rotary actuators per VDI/VDE 3845
• Connections: Cable thread 1/2-14 NPT; air pipe thread 1/4-18 NPT
• Option module: Plug-in analog position feedback, signal range 4…20 mA
• Explosion protection: Without
• Design: Standard varnish / coding

Performance and Environmental Capabilities

• Resolution and linearity: The intelligent positioner delivers stable control across the full 4…20 mA range.
• Response behaviour: Fast air capacity supports quick actuator movement at both 1.4 bar and 6 bar supply pressures.
• Temperature range: The IP 65 aluminium housing protects against dust and water ingress in typical plant conditions.
• Anti-interference: Two-wire technology and NAMUR-compatible digital output reduce electrical noise sensitivity.
• Fail-safe action: The fail freeze output keeps the actuator position on electrical power failure.

Installation Guide

• Check the actuator interface: DIN/IEC 534 / NAMUR for linear, VDI/VDE 3845 for rotary.
• Mount the V18345-1010221001 directly to the actuator using the integrated mounting kit.
• Connect the cable to the 1/2-14 NPT thread and the air pipe to the 1/4-18 NPT thread.
• Wire the two-wire 4…20 mA input and optional digital input/output signals.
• Configure split range, effective direction, and shut-off values through the operator panel.
• Verify air supply pressure: 1.4 bar (20 psi) or 6 bar (90 psi) depending on actuator demand.
