1. Product Overview
2. Product Parameters
| Parameter | Details |
|---|---|
| Input Power | Usually accepts a three – phase AC input. The common input voltage range is around 380 – 480V AC, with a frequency of either 50Hz or 60Hz. This flexibility allows it to be used in different power grid environments around the world. |
| Output Power | The output is a regulated DC power. The output voltage can be adjusted according to the requirements of the generator’s field winding, typically ranging from tens of volts to several hundred volts. The output current can reach up to several hundred amperes, depending on the size and capacity of the generator. |
| Regulation Accuracy | Offers high – precision regulation of the output voltage and current. The regulation accuracy can be within ±0.5% of the set value.

| Efficiency | Designed with high – efficiency power conversion technology. It can achieve an efficiency of over 90%, meaning that a large proportion of the input AC power is converted into useful DC output power. This not only reduces energy losses but also helps in minimizing heat generation, which is beneficial for the long – term reliability of the module. |
| Communication Interface | Equipped with an RS – 485 communication interface. This enables the module to communicate with other control devices in the excitation system, such as the main control unit or a monitoring station. Through this interface, real – time data on output voltage, current, and operating status can be transmitted for remote monitoring, configuration, and diagnostic purposes. |
| Operating Temperature Range | Built to operate within a temperature range of – 20°C to 60°C. This wide temperature tolerance allows it to be used in various environmental conditions, from cold outdoor power plants to warm indoor industrial settings. |

4. Application Areas and Application Cases
- Application Areas
- Power Plants: In thermal, hydro, and gas – fired power plants, the IS200EPBPG1A is used to control the power supply to the generators’ field windings. It helps maintain the proper excitation level of the generators, ensuring stable power output to the grid.
- Industrial Facilities: Large industrial facilities with their own power generation systems, such as manufacturing plants, refineries, and mines, also utilize this module. It enables these facilities to have more control over their power generation and ensures a stable power supply for their critical operations.
- Application Case
- In a hydroelectric power plant, the IS200EPBPG1A is installed in the excitation control system of a 200MW generator. As the water flow through the turbines changes due to seasonal variations or reservoir management, the load on the generator fluctuates. The IS200EPBPG1A can quickly adjust the output voltage and current to the generator’s field winding, maintaining the appropriate excitation level. This ensures that the generator can produce a stable output voltage and frequency, even under varying load conditions, and efficiently supply electricity to the grid.
5. Comparison with Competing Products
- Power Quality: Compared to some competing products, the IS200EPBPG1A offers a higher – quality power output with more stable voltage and current control. This results in better power quality for the generator’s output, which is crucial for sensitive electrical equipment connected to the grid.
- Efficiency: Its high conversion efficiency gives it an edge over many competing products. Lower energy losses mean reduced operating costs and a more environmentally friendly operation.
- Reliability: GE’s reputation for quality and reliability makes the IS200EPBPG1A a more trustworthy choice compared to some competing products. Its ability to withstand harsh operating conditions and provide long – term stable operation is a significant advantage in power generation applications.
- Communication Capabilities: The RS – 485 communication interface allows for better integration and communication with other control devices in the system compared to some competing products that may have limited or no communication features.
6. Selection Suggestions
- Power Requirements: Carefully assess the power requirements of your generator’s field winding, including the input power source available and the specific output voltage and current needs. Ensure that the IS200EPBPG1A can meet these requirements.

IC660ELB912J
High-Speed Gigabit Ethernet Connectivity
The IC660ELB921M provides 1Gbps throughput and dual-port flexibility at approximately 1.5 times the cost of the single-port IC660ELB910, making it ideal for users with high-bandwidth needs. A German automotive assembly plant used 12 IC660ELB921M modules to build a gigabit Ethernet network for its RX3i-based production line control system: each module connected an RX3i rack (equipped with IC695CPU331) to 8 robotic arms and 2 HMI terminals. The 1Gbps throughput supported real-time transmission of robotic motion data (1000 data points per second per robot), and the dual-port design enabled separate networks for control and monitoring—reducing data latency by 70% compared to the IC660ELB910, ensuring precise coordination of the assembly line.
Redundant Ring Network for Uninterrupted Operation
Unlike single-port modules (where a cable break shuts down communication), the IC660ELB921M’s ring topology support ensures network redundancy. A US integrated power plant deployed 18 IC660ELB921M modules in a ring network connecting 18 RX3i racks (controlling turbines, boilers, and generators): when a cable between two modules failed, the network recovered within 250ms, and all control loops continued operating without interruption. This reduced unplanned downtime from 4 hours (with single-port modules) to 0 minutes, avoiding $200,000 in lost power generation revenue per incident.
Multi-Protocol Compatibility for Interoperability
Supporting Modbus TCP, Ethernet/IP, and DNP3.0 protocols, the IC660ELB921M ensures seamless integration with diverse industrial devices. A Chinese smart factory used 8 IC660ELB921M modules to connect its RX3i PLC system with third-party equipment: 4 modules acted as Modbus TCP clients to collect data from Siemens S7-1200 PLCs (controlling conveyors), 2 modules served as Ethernet/IP adapters to communicate with Allen-Bradley VFDs, and 2 modules ran DNP3.0 over IP to send data to the plant’s SCADA system. This compatibility avoided the need for expensive protocol converters (which would have cost $30,000), reducing integration costs by 60%.
Advanced Security and Remote Diagnostics
Equipped with 802.1X authentication and a built-in web server, the IC660ELB921M enhances network security and simplifies maintenance. A Middle Eastern oil refinery deployed 10 IC660ELB921M modules in its hazardous area RX3i systems: 802.1X authentication prevented unauthorized access to the control network, and the web server allowed engineers to remotely configure IP addresses and run ping tests. During a recent maintenance cycle, engineers used the built-in packet capture tool to diagnose a communication issue with a DNP3.0 SCADA link—reducing troubleshooting time by 80% compared to modules without remote diagnostics.
