V18345-2021421101 ABB TZIDC Digital Positioner TZIDC 4-20ma Electric Pneumatic Locator Rugged Design
V18345-2021421101 ABB TZIDC Digital Positioner TZIDC 4-20ma Electric Pneumatic Locator Rugged Design
The ABB V18345-2021421101 is a high-precision electropneumatic positioner from ABB’s trusted TZIDC series, engineered for accurate and reliable control of pneumatic rotary and linear actuators in demanding process automation environments. Designed for use in oil & gas, chemical, power generation, water treatment, and pharmaceutical industries, this smart positioner converts a standard 4–20 mA analog input signal into proportional pneumatic output to precisely position control valves—ensuring optimal flow regulation, energy efficiency, and process stability.
Featuring advanced microprocessor-based control, non-contact position sensing (magnetostrictive technology), and robust IP66/NEMA 4X enclosure, the V18345-2021421101 delivers exceptional accuracy (±0.5% of span), fast response, and long-term reliability—even in harsh conditions with vibration, dust, moisture, or extreme temperatures. It supports split-range control, automatic calibration, and diagnostic functions, reducing commissioning time and enabling predictive maintenance.
