8440-1855 turbine digital governor

Product Description

I. Product overview

The 8440-1855 is a turbine digital governor with overspeed protection from the Woodward brand. It combines advanced digital control technology and overspeed protection to provide an efficient, stable and safe control solution for steam turbines.

Two, the main characteristics

Digital control: The use of advanced digital control technology to achieve accurate and rapid speed regulation function, to ensure that the turbine can run stably under various working conditions.
Overspeed protection: built-in overspeed protection function, when the turbine speed exceeds the set value, it can automatically trigger protective measures to effectively prevent equipment damage and safety accidents.
High reliability: Through strict quality control and testing, to ensure that the product has high reliability and stability, to meet the needs of long-term continuous operation.
Easy maintenance: Reasonable product design, easy maintenance, can reduce maintenance costs and improve equipment utilization.

The control model 8440-1855 is from Woodward’s easYgen-2000 series. The 8440-1855 controller is used to manage the status indicator and all required information is displayed on the display of this controller.

The controller is equipped with 59 terminals, they all have different purposes, if you use an MPU in the controller, it must be connected to terminals 56 and 57, the positive leads will be connected to terminals 56, the negative leads will be connected to terminals 57, incorrectly connecting the leads will affect peak performance.

The power supply is strictly connected to terminal 53, and terminal 54 is also used with the power supply, but a direct power supply should not be used. When connecting the power supply to the terminal 50-tree, the power rating should be 8-40 Vdc.

When installing the control, make sure not to drill holes in the plastic housing, or you will not be able to use the clamping firmware. When operating the inputs on the 3-phase 3-wire setup on the control device and the measuring device, ensure that the rated voltage reading on the control device should be in the range of 50-130 V, or possibly in the range of 131-480 V, depending on the control device used.
