FUNCTIONAL DESCRIPTION:

DS215DKLAG1AZZ01A is an I/O Supervisor Module manufactured and designed by General Electric as part of the Series used in the R, S, and T cores of the GE Mark V Speedtronic Gas Turbine Control Systems. It functions as a communication and data coordination hub between the main control processor and field-level I/O devices. The IOS module collects analog and digital data from field instruments, performs initial signal conditioning, and transmits this data to the control processors. In reverse, it delivers processor commands to the field actuators. It also supervises diagnostic checks and ensures synchronization across redundant controllers in TMR (Triple Modular Redundancy) systems. Its robust design and processing capability support real-time monitoring and high-speed data exchange essential for safe and efficient gas or steam turbine operation.

INSTALLATION:

The IOS module is designed to be installed into a dedicated slot on the Mark V backplane (core R, S, or T). Installation should be performed only when the system is completely powered down to avoid electrical hazards or damage to sensitive components. The card is inserted vertically into the slot and mates with an edge connector that links it to the backplane’s power and data bus. The user should ensure correct orientation and secure the module using any provided brackets or screws. After physical installation, ribbon cables or terminal connectors from terminal boards (e.g., TBQC, TBCA, TBCC) are attached to the IOS. Once powered on, the module begins its boot-up sequence and undergoes system diagnostics automatically. Correct installation can be confirmed through the i operator interface.

OPERATION:

The IOS module acts as a central hub that constantly supervises and coordinates data flow between the controller CPUs (such as the DCC and C cores) and the I/O terminal boards. It digitizes analog signals, handles digital I/O, performs fault detection, and ensures signal integrity across the system. In redundant configurations, it synchronizes inputs between cores and enables voting logic to determine the most reliable signal paths. The module also supports real-time diagnostics and alarms, detecting open circuits, communication failures, or incorrect signal ranges.

COMPATIBILITY:

The DS215DKLAG1AZZ01A module is designed to be fully compatible with both DS200 and DS215 series backplanes. This means it can be directly inserted into the existing control racks of either system without requiring modifications. It matches the physical dimensions, power requirements, and connector layout of both backplane types, ensuring seamless hardware integration.

• System Compatibility: This IOS module is suitable for use in both Simplex (single controller path) and TMR (Triple Modular Redundant) configurations within GE Mark V turbine control systems. In Simplex setups, it handles all input/output functions independently, while in TMR systems, it works in coordination with two other modules to ensure redundancy, fault tolerance, and high system reliability.

• Processor Compatibility: The module is engineered to interface smoothly with GE Mark V control processors such as DCC, DCCX, and related CPUs. It communicates directly with these processors to exchange I/O data, support logic execution, and maintain real-time system synchronization. Its firmware and architecture are fully aligned with the data protocols and timing used by these control cores.
