Performance and Environmental Capabilities

• The positioner offers high resolution and stable linearity for precise valve control.
• It maintains reliable performance across a wide temperature range in industrial environments.
• The IP 65 / NEMA 4X housing resists dust, water, and harsh plant conditions.
• Two-wire technology reduces wiring complexity and improves signal integrity.
• The analog position feedback module provides real-time valve position data.
• Digital input and output support NAMUR-compatible control circuits.
• The fail-freeze output keeps the actuator in its last position on power loss.
• Split range configuration allows flexible integration into existing control loops.

Installation Guide

• Mount the positioner directly to linear actuators per DIN/IEC 534 / NAMUR standards.
• For rotary actuators, use the VDI/VDE 3845 interface for a secure fit.
• Connect the 4...20 mA two-wire input using the LKS adapter plug.
• Use M20 x 1.5 cable thread and 1/4-18 NPT air pipe thread for connections.
• Verify supply pressure stays within 0...6 bar (0...90 psi) for safe operation.
• Check the shut-off values and configure end positions before commissioning.
• Confirm the analog position feedback signal range matches your control system.
• Test the fail-freeze action during electrical power failure simulation.

FAQ

• Q: What is the input signal range of the V18345-1010551001?
  A: The unit accepts a two-wire 4...20 mA signal with split range configuration between 20% and 100%.
• Q: Does this positioner support both linear and rotary actuators?
  A: Yes, it mounts to linear actuators per DIN/IEC 534 / NAMUR and rotary actuators per VDI/VDE 3845.
• Q: What is the maximum air capacity at 6 bar?
  A: The air capacity reaches 13 kg/h = 10 Nm3/h = 6.0 scfm at 6 bar supply pressure.
• Q: What happens when electrical power fails?
