Product Overview
The GE 4136J57-G01 functions as a dedicated dual setpoint board for the GE Speedtronic Mark III gas turbine control system . This board compares measured process parameters against operator-defined setpoints for closed-loop on-off control . Moreover, the 4136J57-G01 provides discrete alarm and control outputs through configurable relay interfaces.
Technical Specifications
The 4136J57-G01 operates on a 250 VAC supply and supports a frequency range of 15 Hz to 70 Hz . This board weighs 2.00 lbs and measures 19.00 x 12.50 x 3.50 inches in its standard Mark III format . Additionally, the unit operates reliably across a temperature range of 0°C to 60°C .

Key Design Features
The 4136J57-G01 supports two optional plug-in setpoint controller boards for enhanced configurability . One option features dual electromechanical relays rated at 8 amps and 250 volts . The alternative option provides dual solid-state relays designed for heavy-duty cycles with light loads . Consequently, engineers can select the relay type that best matches their specific alarm or control application. The solid-state version effectively eliminates contact wear, making it ideal for frequent switching operations . Furthermore, the board supports interface with Micro DPMs, counters, and remote display modules .
Application and Integration
The 4136J57-G01 integrates into Mark III turbine control cabinets for gas turbine management applications . This board continuously evaluates incoming signals against predefined setpoints, toggling output states instantly when deviations occur . As a result, it plays a vital role in overspeed protection, temperature monitoring, and pressure control loops. Technicians must isolate primary system AC power before removing or inserting the board to prevent arcing across edge connector pins .
