Description

The 8237-1660 is a panel-mount ProTech-GII overspeed protection device designed for steam, gas, and hydro turbines. It monitors turbine rotor speed and acceleration, issuing shutdown commands to the turbine's trip valve(s) upon detecting overspeed or over-acceleration events. This model supports high voltage (HV/HV) inputs with voted relay outputs and offers limited functionality compared to full models.

Features

Triple Modular Redundancy: Ensures no single-point failure affects system reliability.
Voted Inputs and Relays: Uses 2-out-of-3 voting logic for critical decisions.
Modbus Communication: Facilitates data exchange and configuration.
Automated Testing: Includes predefined test routines for system verification.
Limited Functions: Offers a subset of features tailored for specific applications, focusing on essential safety functions.
