Ordering Code Breakdown (Tree View)
- V18345 = TZIDC intelligent positioner with display and keypad
- 10 = Aluminum case IP65, no mechanical indicator
- 2 = 4-20mA with LKS adapter plus FSK module for HART
- 1 = FM/CSA explosion protection
- 1 = Double acting, fail freeze
- 2 = Electrical 1/2-14 NPT, Air 1/4-18 NPT
- 0 = No analog feedback
- 00 = No mechanical feedback
- 1 = Standard design
Installation Guide
- Mount the positioner on the valve assembly.
- Connect air supply to 1/4-18 NPT or G 1/4 ports.
- Wire 4-20 mA signal to screw terminals.
- Do not put strain on the terminal wires.
- Use cable glands on the 1/2-14 NPT threads.
- Keep one thread with a pipe plug if not used.
- Close the housing properly for IP65 protection.
HART Communication Setup
- The FSK module enables HART communication.
- Connect a HART modem to the 4-20 mA loop.
- Use HART handheld or PC software for configuration.
- Read live valve position data remotely.
- Adjust parameters without opening the housing.
Environmental Tolerance
- Works in very cold temperatures down to -40°C.
- Handles hot environments up to +85°C.
- High humidity up to 95% is fine. Condensation is allowed.
- IP65 case keeps dust and water jets out.
- Epoxy varnish coating resists corrosion.
Electrical Connections – Important Notes
- Screw terminals accept wires up to 2.5 mm² for analog signal.
- Options wiring uses max 1.0 mm².
- Never put strain on the terminals. Use cable ties nearby.
- Two cable entries available: 1/2-14 NPT or M20x1.5.
- One entry comes with cable gland. The other has a pipe plug.
Compatibility
- Works with any pneumatic valve actuator.
- Accepts standard 4-20 mA control signals from any DCS or PLC.
- Double acting output suits double-acting actuators.
- HART communication works with any HART master device.
- FM/CSA approval allows use in hazardous locations.

Professional FAQ
- Q: What is the difference between V18345-1021120001 and V18345-1010521001?
- A: This model adds HART communication (digit 2) and FM/CSA explosion protection (digit 3). The other model has neither.
- Q: Can I use this positioner in very cold climates?
- A: Yes. It works down to -40°C. Perfect for outdoor winter applications.
- Q: What happens to condensation inside the housing?
- A: Condensation is allowed. The electronics can handle it when the housing stays closed.
- Practical tip from engineers:
- Always use shielded cable for the 4-20 mA loop with HART. Noise can disrupt HART communication.
- Selection guide for buyers:
- Choose V18345-1021120001 for hazardous locations needing FM/CSA approval and HART.
- Do you need analog position feedback? Pick digit 7 = 1 instead of 0.
- No explosion protection needed? Select V18345-1011120001 (digit 3 = 0).
- Need single acting fail close? Change digit 4 to 4 instead of 1.
- Confirm your thread type. This model uses NPT. Choose metric threads if needed (digit 5 option).
