GE DS200TCRAG1AAA Relay Output Board

الوصف

The GE DS200TCRAG1AAA Relay Output Board is an essential component designed by General Electric for use in industrial control systems, specifically as part of the Mark V LM Series of microprocessor-based aero-derivative turbine control systems.¹

Key Features and Function

• Function: It is a Relay Output Board (TCRA) that controls and manages relay outputs.² Its primary role is to provide reliable switching and integration to interface with and control external devices or systems based on relay signals.³ This is integral to automating processes and executing control commands.⁴
• Location: The TCRA boards are typically located in the digital cores of the control system.⁵
• Relays: The board is often populated with up to 30 plug-in relays (K1 through K30).⁶ However, the number of active relays can vary based on its specific location within the core (e.g., in one location, a board may contain only four relays).⁷
• Power & Logic:
  • Power Requirements: Typically ⁸$+5 \text{ V dc}$ at ⁹$6 \text{ A}$.¹⁰
  • Logic Levels: ¹¹$3.3 \text{ V}$ and ¹²$5 \text{ V}$ compatible.¹³
• Connectors: The board features multiple connectors, including ¹⁴$4$ ¹⁵$\text{34-pin}$ connectors (like JOR, JOS, JOT, and JO) and ¹⁶$4$ ¹⁷$\text{12-pin}$ connectors (like JS3, JS4, JS5, and JS6).¹⁸
• Configuration: Some relays, particularly the first 18 or 16 depending on the board’s location, can be configured via hardware jumpers on associated terminal boards (DTBC and DTBD) to provide a power source to operate solenoids.¹⁹
• Protection: The board typically features a normal PCB coating for standard protection against environmental contaminants like dust, ensuring reliable performance in industrial settings.²⁰
