FAQ

• Q: What is the input signal range of the V18345-1010251001?
  A: The unit accepts a two-wire 4...20 mA signal with LKS adapter connector plug.
• 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 supply pressure range?
  A: The supply pressure range is 1.4...6 bar (20...90 psi), and you must not exceed the actuator's maximum pressure.
• Q: What happens when electrical power fails?
  A: The single-acting output provides fail freeze, so the actuator holds its last position.
• Q: What is the resolution of the A/D conversion?
  A: The resolution exceeds 4000 steps for precise valve positioning.
• Q: Is the analog position feedback module included?
  A: Yes, this configuration includes a plug-in analog position feedback module with 4...20 mA signal range.
• Q: What are the cable and air pipe thread sizes?
  A: The cable thread is M20 x 1.5, and the air pipe thread is 1/4-18 NPT.
• Q: How does vibration affect the positioner?
  A: Vibration influence stays within ± 1% up to 10 g and 80 Hz.
• Q: How long does shipping take?
  A: We dispatch within 5 days and use FedEx, UPS, or DHL for delivery.
