Products 8237-1597 can be equipped with turbines of any size and can be safely shut down in the event of unsafe acceleration. The bulkhead bracket is used in conjunction with steam, gas, and hydraulic turbines and has three independent relays. It also adopts a two out of three architecture, as well as high and low voltage power input. Other detailed information about models 8237-1597 includes; It is part of the Protech GII series. A speed reading of 4 to 20 mA. MPU and acceleration detection. Conformal coatings can resist sulfur pollution. Can be used in Class 3C2 environments. Easily integrated into any size of turbine. Models 8237 1597 are equipped with online repair options, which can work on one module while the entire system is still running. The backplane structure also makes it easy to work on this device. The Woodward safety device can also perform routine checks to ensure that each module is functioning properly. This is accomplished through an internal generator and frequency, and the results of these tests can be stored. Woodward no longer manufactures or sells models 8237-1597, but it can be found through AX Control. AX Control can repair, purchase, or sell these turbine safety models. Woodward 8237-1597 ProTech-GII Bulkhead Installation, HV/HV, Voting Relay, Voting Input Depending on the model purchased, the ProTech-GII comes in a Bulkhead Mount or Panel Mount Housing Package. The partition mounted housing model is designed for installation on walls or bases next to turbines or equipment, rated for IP56 based environments. For these models, field wiring access is done through a gland plate located at the bottom of the casing. Figures 2-1, 2-2, and 2-3 show the physical layout and installation mode of the ProTech-GII model with partition installation. ProTech ®- The GII overspeed protection device Woodward’s ProTech-GII is an overspeed safety device designed to safely shut down steam, gas, and water turbines in the event of an overspeed or acceleration event being detected. This device accurately monitors the speed and acceleration of the turbine rotor through active or passive MPUs (magnetic sensors), and issues a shutdown command to the turbine’s trip valve or corresponding trip system. ProTech-GII has passed IEC61508 SIL-3 certification and complies with API670 and API612 standards
