ABB V18345 TZIDC Digital positioner

If you’re looking for detailed technical specs of the ABB V18345 TZIDC Digital positioner, we’ve got you covered with clear, straightforward details—no complicated jargon, just what you need to know. First off, the ABB V18345 TZIDC Digital positioner is an electro-pneumatic intelligent positioner, designed to work seamlessly with both linear and rotary actuators for various industrial valves. Let’s break down its key technical parameters. For operating temperature, the ABB V18345 TZIDC Digital positioner performs reliably in extreme ranges from -40°C to +85°C, making it perfect for harsh industrial environments like arctic oil fields or high-temperature refineries. Its supply pressure ranges from 1.4 to 6 bar (20 to 90 psi), with a marine version option of 1.6 to 5.5 bar, and it has ultra-low air consumption of less than 0.03 kg/h, helping you save energy costs.

When it comes to control accuracy, the ABB V18345 TZIDC Digital positioner stands out with a base accuracy of ±0.5% of span and repeatability of ≤±0.1% FS, thanks to its TEIP11 core component and adaptive PID control algorithms. It supports a travel range of 20-150 mm for linear actuators and up to 270° for rotary actuators, fitting most globe, ball, and butterfly valves. The ABB V18345 TZIDC Digital positioner uses a 4–20 mA DC two-wire input signal and supports HART protocol (compatible with HART 7) for easy integration with DCS systems, plus optional digital I/O for alarm and emergency shutdown functions.

In terms of design and durability, the ABB V18345 TZIDC Digital positioner has an IP65/IP66-rated aluminum housing with anti-corrosion coating, resisting dust, moisture, and vibration up to 10 g (10-150 Hz). It features a fast response time of less than 1 second for full-stroke step response and offers fail-safe modes (fail-freeze or fail-safe) to prevent process disruptions when power or air supply is lost. The ABB V18345 TZIDC Digital positioner also has a compact, modular design, with 1/4-18 NPT air connections and 1/2-14 NPT electrical connections, and it can be easily configured via its built-in LCD panel or remote HART communication.
