Valve opening display table WP-D935 operator: It can automatically follow the input value to adjust the control output, and can have one analog control output, one switch control output (can control forward/reverse), and one analog tracking output. Can achieve automatic/manual undisturbed switching. When manually switching to automatic mode, an approximation algorithm is used with a switching limit function to ensure smooth switching between manual and automatic modes.
Valve opening display tableProduct Description: How to Translate
The intelligent manual operator uses a microprocessor for intelligent control and can be connected to various regulators as a backup control instrument. Once the regulator control fails, it can be manually operated and controlled by this controller, and can replace the servo amplifier to directly drive the electric or pneumatic actuator. It can simultaneously input and display measurement signals and feedback signals. And the input port has signal input function, which can easily switch between different types of input signals (various thermocouples, thermistors, standard signals) through simple selection in the instrument menu, improving the universality and reliability of the instrument.
Adopting high brightness LED digital display and high-resolution light column display (proportional display), clear and intuitive. There are two display modes: dual screen digital display; Dual screen digital display+dual light column display (displaying measured values+valve position feedback values/output values). The input/output circuits are both optically isolated and can be equipped with serial communication interfaces.
