8237-1596 ProTech-GII 8237-1596 Bulkhead Mount

Model 8237-1596 over-speed detection device from Woodward. It’s part of the Protech-GII series and

can work with any size turbine powered by water, gas, or steam. It uses two redundant relays, and two out

of three voted architecture. This triple modular design works to sense and safely shut down turbines if they over

accelerate in an unsafe manner. Model 8237-1596 is also equipped with Modbus communication and is designed with

easy integration in mind.

This product is a bulkhead mount that uses high- and low-voltage power

inputs. Speed readouts for this safety system are from 4 to 20 mA. Model 8237-1596 is configured with MPU detection in addition to acceleration detection.

With the triple modular design,  any module can be repaired when the system is still online. The protective

coating on this device keeps it resistant to sulfur contamination. It can be used in class 3C2 environments and is protected

in the long term from SO2 and H2S gases. An internal generator in this safety system can perform routine speed checks on

each module. The results of these tests will then be stored in the device’s memory.
