Technical Specifications 4‑20 mA control signal input, position feedback signal input, pneumatic drive output control. Auxiliary power taken from loop signal, typical power consumption 2.3 W. Operating temperature ‑20 ℃ to +85 ℃, storage temperature ‑40 ℃ to +85 ℃. Conformal coated printed circuit board.
Functional Features Receives remote valve opening set‑point signal. Compares set‑point value and actual valve position feedback. Outputs control signal to drive pneumatic relay assembly. Supports positioner parameter setting and automatic stroke calibration. Built‑in hardware self‑diagnosis function.
Application Scenarios Replacement spare‑part for ABB intelligent valve positioners. Used for maintenance work of petrochemical, power and chemical industry field control valves.
Performance Parameters Rapid closed‑loop adjustment response. High‑precision signal processing ensures valve positioning accuracy. Self‑diagnosis detects internal circuit and signal loop faults.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Microprocessor, signal conditioning components. Conformal protective coating. Multi‑pin plug‑in connection terminals.
Structural Characteristics Compact circuit board matching positioner internal installation space. Equipped with plug‑in connectors for feedback sensor and pneumatic drive parts. Reserved mechanical fixing holes. Weight approximately 0.19 kilogram.
Working Principle After power‑on, control board completes hardware self‑check. It receives remote opening set‑point signal and actual valve position feedback signal. Internal processor calculates deviation value and outputs drive signal to pneumatic relay, adjusting air pressure for actuator until valve position matches set‑point value.
Installation Requirements Disconnect field control signal and instrument air supply before replacement. Install V17152310 inside positioner housing and tighten fixing screws. Fully insert and lock all plug‑in connectors. Restore signal and air supply. Complete valve stroke calibration and parameter verification.
Usage Notes Take anti‑static measures during handling. Avoid damage to conformal coating. Execute stroke calibration after each board replacement. Ensure positioner housing maintains good sealing performance.
