The DS200TCRAG1ACC is applicable in any turbine control architecture that necessitates robust, discrete relay outputs with high reliability and straightforward integration into networked control systems. It addresses control challenges including relay isolation, high surge endurance, and durable contact switching required in harsh industrial environments.
Product Introduction & Positioning
The GE DS200TCRAG1ACC is a discrete relay output board featuring 30 plug-in relays, engineered specifically for the Speedtronic Mark V series turbine control platform. This module provides a high number of relay outputs within a compact design, facilitating efficient control of turbine auxiliary devices such as solenoids, indicators, and interlock systems. Positioned as a vital part of Mark V control racks, the DS200TCRAG1ACC offers direct and reliable relay activation capabilities that are crucial for the execution of turbine control logic.
Its design emphasizes modularity and ease of replacement. The plug-in relay assemblies enable quick maintenance and the discrete output grouping supports effective signal segregation for fault isolation. The DS200TCRAG1ACC integrates seamlessly with Mark V PLC CPUs and other control components, making it an indispensable element in turbine automation systems where precision and uptime are paramount.
Key Technical Features & Functional Benefits
The GE DS200TCRAG1ACC incorporates 30 plug-in relays, each capable of handling a contact rating of 6 amperes at 250 VDC and 10 amperes at 125 VAC. This high load capacity enables the module to switch a variety of electrically demanding turbine auxiliary components. The discrete relay outputs are organized via four 34-pin connectors and four 12-pin connectors, allowing for efficient wiring and expansion.
Operating typically at 12 VDC with an input current of approximately 200 mA, the board maintains low power consumption while delivering robust switching performance. Its relay contacts provide high surge resistance and long mechanical life, critical for industrial reliability. The module’s physical design supports easy slot replacement and minimizes downtime during service.
