ProTech-GII is an overspeed safety device designed to safely shut down steam, gas, and hydraulic turbines of various sizes when an overspeed or over acceleration event is detected. Feature: Acceleration detection: ProTech-GII can also be configured to protect the turbine from high acceleration events. The derivative of the speed signal is used to detect turbine acceleration and issue relevant trip commands. Main control board detection: Each module’s speed sensor input uses a special MPU open line detection circuit to verify whether the MPU is correctly connected before turbine operation, and uses a special stall detection logic to verify the MPU function during turbine operation. Automatic overspeed testing program: Alternatively, ProTech-GII can be configured to perform periodic overspeed testing on each module, and then record and report the test results. Through this testing routine, each module will use an internal frequency generator to simulate overspeed conditions and complete its testing sequence. ProTech-GII uses a special conformal coating material, which has excellent long-term protection against H2S and SO2 gases, and its level complies with the international standard IEC 721-3-3 1994-environmental level 3C2. The triple module design of ProTech-GII allows users to easily replace one of the modules (A, B, C) while the turbine is online and running normally.

The plug and play structure of the device’s backplane and its inter module learning function enhance the convenience of replacement. ProTech-GII is a configurable overspeed detection system designed to safely shut down steam, gas, and hydraulic turbines of various sizes when an overspeed or over acceleration event is detected. Provide two dual redundant trip relay outputs using a 3-to-2 voting architecture, or three independent non voting trip relay outputs with separate alarm relays, 4-20 mA speed readings, and Modbus ® Communication makes it possible for this overspeed device to be easily integrated into any turbine safety system. This ProTech GII model is a panel mounted, high/low voltage power input, voting relay/voting input safety device used for steam turbine overspeed protection. The 8237-1600 model can be configured for use with turbines of any size, as long as it is powered by steam, natural gas, or water. The speed reading of the over acceleration device is between 4 and 20 mA. If a turbine of any size begins to accelerate dangerously, the model will safely shut it down.

The panel installation has a backboard structure, which is easy to maintain and replace. The 8237-1600 model can be easily integrated into any turbine system and is equipped with Modbus communication function. In addition to acceleration detection, it is also equipped with MPU detection. The coating of this product enables it to resist sulfur pollution and can be used in 3C2 level environments. It has the IEC 721-3-3 1994 international standard. It uses three independent trip relays as well as low-voltage and high-voltage power inputs. Models 8237-1600 also use a two-thirds voting architecture. The overspeed detection device adopts a three module design, which can be repaired when the system is online. A module can run simultaneously with two other modules. Products 8237-1600 can also perform routine speed tests using an internal generator and frequency.
