5 Professional FAQs
- What is the advantage of the mechanical position indicator on this model?
- You can see valve position locally without power. Great during maintenance or power loss.
- Does this positioner support HART communication?
- Yes. It supports HART Protocol 5.1. Use FSK modem for remote access.
- Can I configure custom characteristic curves?
- Yes. You can set up to 20 reference points for custom curves.
- What happens if my air supply has oil or water?
- Dirty air damages internal parts. Always use filter regulator to meet Class 3 purity.
- Do you offer the analog feedback module for this unit?
- This model comes without feedback. Please contact us if you need 4-20 mA feedback option.
Selection Guide – Pick the Right TZIDC Positioner
- Step 1 – Need local visual position? Choose code 2 (this model) for mechanical indicator. Code 1 has no indicator.
- Step 2 – Explosion protection needed? Code 0 has no protection. For hazardous areas, pick codes 3, 5, or 6.
- Step 3 – Output type: Code 4 gives double acting fail safe. For single acting, pick other codes.
- Step 4 – Feedback needed? Code 0 has no feedback. Add code 1 for analog 4-20 mA feedback.
- Step 5 – Connection type: Code 2 gives NPT threads. For metric G threads, choose code 1.
- Pro tip: For HART networks, ensure your DCS has built-in HART multiplexer or external FSK modem.
