Detailed introduction
Introduction to ABB Valve Positioner V18345-1010221001:
Here’s a crisp summary of the key features of the ABB TZIDC-120 Valve Positioner (V18345-1010221001):
Control Signal: 4–20 mA with HART communication, enabling remote configuration and diagnostics
Fail-Safe Behavior: Fail-freeze on power loss—keeps the valve in its last position
Mounting Versatility: Fits both linear and rotary actuators (DIN/IEC 534, NAMUR, VDI/VDE 3845)
Housing & Protection: Aluminum construction with IP65 (NEMA 4X) rating for harsh environments
Pneumatic Output: Single-acting output for precise control of air to the actuator
Local Interface: Pushbuttons and LCD for easy on-site configuration and calibration
Feedback Options: Optional analog position feedback (4–20 mA) and limit switches
Communication Protocols: HART standard; supports advanced diagnostics via asset management systems
Certifications: FM, CSA—approved for use in hazardous environments

Frequently Asked Questions – ABB TZIDC-120
1. What type of signal does the TZIDC-120 accept?
It operates on a 4–20 mA analog signal and supports HART communication for remote diagnostics and configuration.
2. Can it be used with both linear and rotary actuators?
Yes, it supports mounting on both linear (DIN/IEC 534 / NAMUR) and rotary (VDI/VDE 3845) actuators.
3. What happens during a power failure?
The positioner enters a fail-freeze mode, maintaining the last valve position to avoid process disruption.
4. Is it suitable for hazardous environments?
Absolutely. It carries FM and CSA certifications for use in hazardous areas.
5. What kind of feedback options are available?
It offers optional analog feedback (4–20 mA) and mechanical limit switches for position monitoring.
6. How is it configured on-site?
Via a local LCD interface with pushbuttons, allowing easy calibration and diagnostics without external tools.
7. What’s the enclosure rating?
It’s rated IP65 / NEMA 4X, making it dust-tight and resistant to water jets—ideal for harsh industrial settings.
8. What are the pneumatic and electrical connection types?
Pneumatic: 1/4-18 NPT Electrical: 1/2-14 NPT
9. Does it support remote asset management?
Yes, through HART protocol, it integrates with asset management systems for predictive maintenance and monitoring.
10. What’s the operating temperature range?
Typically –40°C to +85°C, depending on the specific configuration.
