Product Overview

The DS200TCEBG1ACE is a specialized Protective Termination Expander Board developed by General Electric for the Speedtronic Mark V turbine control series. Functioning as a high-speed emergency trip interface, this board is an integral safety layer for steam and gas turbine operations. It is specifically designed to manage expansion circuit terminations that require ultra-fast protective responses, achieving an execution speed of under 10 milliseconds. By bridging critical sensor inputs and emergency shutdown logic, the DS200TCEBG1ACE ensures that protective sequences are triggered with absolute precision, safeguarding expensive rotating machinery from catastrophic failure during transient events or mechanical overspeeds.

Essential Hardware Features and Environmental Ratings

This Protective Termination module is built to maintain signal integrity while operating in the rigorous conditions typical of power generation facilities:

• Isolation Protection: Engineered with a high dielectric strength providing electrical isolation up to 1500 VAC, protecting the control core from field-side surges.

• Response Dynamics: High-speed logic gates allow for emergency trip signal propagation in less than 10ms.

• Thermal Endurance: Rated for continuous operation in extreme temperatures ranging from -40°C to +70°C.

• Power Efficiency: Consumes a nominal 8W of power while operating on a standard 24VDC (±10%) industrial supply.

• Input Compatibility: Optimized for 24VDC digital input signals, facilitating direct connection to protective field contacts and switches.

• Atmospheric Resilience: Capable of functioning in non-condensing humidity levels between 5% and 95% RH.

• Mechanical Profile: Standardized dimensions of 28 x 21.4 x 2 cm with a total unit weight of 0.6 kg, designed for efficient mounting within VME-style control racks.

Primary Industrial Roles and Safety Context

The DS200TCEBG1ACE serves as a critical node in the turbine's failsafe architecture. Its deployment is centered around high-reliability protection tasks:
