ALP2100-SERIES sart positioner Description

1. Overview

1.1  Performance  profile  of  the  ALP210  The  ALP210  uses  a  microcontroller electronic control unit, the PID exact algorithm of the  pneumatic instrument. With keys, LCD dot array screen display, HART  communication and MSBUS communication functions. Adopt modular structure, compact, strong, reasonable design. High cost performance, simple  maintenance, to avoid unnecessary user costs.

operation panel

ALP locator built-in operation panel, equipped with 3 keys and LCD LCD display, simple and convenient operation. With simple debugging and automatic, manual operation switching function. Can facilitate the stroke adjustment and automatic sealing function to open and close. You can also view the run parameters.

Pneumatic performance

With many years of experience in pneumatic instrument design, the carefully optimized single-action and dual-action amplifier structure brings great convenience to users and saves the use cost. Modular structure, easy to repair, replacement. The ALP locator is equipped with two output interfaces, blocking an output interface is a single-action valve positioner, and can also change the interface to change the form of the valve action.

communication

ALP has two modes of communication, MSBUS can be used to connect to  a dedicated operator or computer, HART communication module (not standard, selected when purchase) can be connected to HART operator or (through  HART-adjustment demodulator) to the computer.
