Performance and Environmental Durability

• The positioner delivers stable control with a 4–20 mA input signal and low minimum current draw.
• It supports split range configuration between 20% and 100% of the nominal range.
• The IP 65 / NEMA 4X aluminium housing resists dust, water spray, and harsh plant conditions.
• Digital input and output circuits follow NAMUR logic for reliable signal exchange.
• The output stage handles single or double acting actuators with fail-freeze behavior.
• Air capacity reaches 13 kg/h at 6 bar supply pressure for fast actuator response.

Installation Guide

• Mount the positioner to linear actuators per DIN/IEC 534 / NAMUR or rotary actuators per VDI/VDE 3845.
• Use the integral mounting option when the actuator interface allows direct attachment.
• Connect the air pipe with 1/4-18 NPT thread and the cable with 1/2-14 NPT thread.
• Wire the two-wire input to a 4–20 mA loop and observe the maximum 30 V DC limit.
• Set the split range if the application uses only part of the 4–20 mA signal.
• Verify the fail-freeze output action before commissioning the control loop.

FAQ

• Q: What is the input signal range of the V18345-1010221001?
  A: It uses a 4–20 mA two-wire input with a nominal range of 4–20 mA.
• Q: Does this positioner support split range operation?
  A: Yes, you can configure split range between 20% and 100% of the nominal range.
• Q: What is the air output range?
  A: The output range is 0–6 bar, which equals 0–90 psi.
• Q: Can I use it with 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 happens when electrical power fails?
  A: The single acting output provides fail freeze, so the actuator holds its last position.
• Q: What are the air and cable connection threads?
  A: The air pipe uses 1/4-18 NPT and the cable uses 1/2-14 NPT.
• Q: Is analog position feedback included?
  A: Yes, the option module provides analog position feedback with a 4–20 mA signal range.
• Q: How fast do you ship?
  A: We keep stock available and ship within 5 days using DHL, FedEx, or UPS.
