GE 44A751101-G01 Single Board Computer Module

GE 44A751101-G01

The GE 44A751101-G01 is an I/O communication expansion module belonging to the General Electric (GE) Mark VIe Speedtronic™ series, specifically designed for control systems of large rotating machinery such as gas turbines and steam turbines. As a key component of the distributed I/O architecture, this module enables high-speed data communication between controllers and remote I/O stations, supporting real-time control signal transmission and monitoring data acquisition.

Core Values of 44A751101-G01

High-Speed Communication: Adopts industrial Ethernet protocols (e.g., SRTP or Modbus TCP) to ensure low-latency and high-bandwidth data exchange.
Redundant Design: Dual RJ45 ports support ring network redundancy (HSR/PRP), enhancing system reliability.
Seamless Integration: Natively compatible with GE Mark VIe controllers (e.g., IS200ERMG), simplifying system configuration.

Structure and Composition

The 44A751101-G01 features a compact industrial design, with main components including:

Ethernet Communication Chip: A high-performance processor that supports real-time industrial protocols (e.g., SRTP) and standard TCP/IP communication.
Dual RJ45 Ports: Provide redundant network connections, support ring network topology (HSR/PRP), and enhance communication reliability.
Backplane Interface: A high-speed connector that interacts with the Mark VIe rack backplane to obtain power and transmit data.
Status Indicators: LEDs display power status, network activity, and fault conditions for quick diagnostics.
Metal Enclosure: Offers EMC shielding and mechanical protection, complying with industrial anti-vibration standards.

Key Features and Advantages

High-Reliability Communication
- Supports Gigabit Ethernet, meeting the high-bandwidth requirements of real-time control data with latency below 1ms.
- Features dual-network-port redundancy design, supporting HSR/PRP ring networks to avoid system outages caused by single-point failures.
Seamless Integration with Mark VIe Systems
- Natively compatible with GE Mark VIe controllers (e.g., IS200ERMG), eliminating the need for additional protocol conversion.
- Enables easy configuration of network parameters and I/O mapping via ToolboxST software.
Enhanced System Scalability
- Supports connection to up to dozens of remote I/O stations, significantly reducing on-site wiring costs.
- Flexibly adapts to various I/O modules (e.g., analog input IC693ALG390 or digital output IC693MDL654).
Industrial-Grade Durability
- Wide operating temperature range (-20°C to +70°C), suitable for harsh environments such as power plants and offshore platforms.
- Complies with the IEC 61800-3 standard, offering strong electromagnetic interference (EMI) resistance.

Installation and Maintenance

Pre-Installation Preparation

Ensure the Mark VIe rack is powered off (or supports hot swapping), and wear an anti-static wristband.
Review the network topology diagram and plan the connection sequence of RJ45 ports (to avoid ring network logic conflicts).

Maintenance Recommendations

Regularly check the network connection status (via LEDs or software diagnostic tools).
Clean the module’s heat dissipation holes to prevent dust accumulation from affecting heat dissipation.
