Model 8237-1247 is part of the Woodward Protec-GI series. Such septum

The plate mounting method is used to detect overspeed of various types of turbines. It can be configured with water

The force, steam and gas turbines work together to shut down safely in the event of excessive acceleration

They’re. It has a speed reading of 4 to 20 mah and uses Modbus for communication. The property

The product can be installed in a standard cabinet door and uses two multi-trip relays. It uses high electricity

Voltage and high voltage power input.

Features and functions

8237-1247 Acceleration detection

In addition, the 8237-1247 can be configured to protect the turbine from high acceleration events. The derivative of the speed signal is used to detect the turbine acceleration and issue the relevant trip command.

MPU detection. Each module’s speed sensor input uses a special MPU open detection circuit to verify that the MPU is properly connected prior to turbine operation, and a special speed loss detection logic to verify during turbine operation

MPU function.

Automatic overspeed test program. Alternatively, ProTech-Gl can be configured to perform routine overspeed tests on each module and then record and report the test results, in this test routine, each module completes its test sequence using an internal frequency generator to modulus

Probable speeding condition.
