Product Description


GE 151X1235DB15SA01 EX210E | EX2100e Regulator PCM (Power Control Module)
Precise Excitation Control, Voltage Regulation & Generator Synchronization for Power Generation Systems
1. Product Overview

The GE 151X1235DB15SA01 EX210E is a Regulator PCM (Power Control Module) integrated into the GE EX2100e Excitation Regulator system, engineered to deliver precise excitation control, field voltage regulation, and generator synchronization for synchronous generators in power plants, industrial facilities, and renewable energy installations. As a core component of the EX2100e system, this module provides closed-loop control of generator field current, maintaining stable terminal voltage under varying load conditions (grid fluctuations, reactive power changes, and transient events). It supports multiple control modes (manual, automatic, and remote), seamless synchronization with grid systems, and compatibility with GE Mark VIe turbine control platforms for integrated power generation management. The PCM features advanced digital signal processing (DSP) for high-speed control response (<10ms), redundant hardware architecture for fault-tolerant operation, and built-in protection functions (overexcitation, underexcitation, overvoltage, overcurrent, and field failure protection) to ensure generator and system safety. With a wide operating temperature range (-25°C to +70°C), conformal-coated PCB for environmental protection, and compliance with IEC 61850, IEEE 421.5, and NERC standards, the 151X1235DB15SA01 EX210E is ideal for utility-scale power generation, combined-cycle plants, and industrial cogeneration systems requiring reliable excitation control and grid stability.

4. Installation & Maintenance
Installation: Mount the PCM in the EX2100e regulator cabinet on standard 19-inch racks; connect field current sensors, voltage transformers, and control power (24V DC redundant input). Configure control modes, voltage setpoints, and protection thresholds via EX2100e HMI or software. Verify communication with Mark VIe controllers and grid SCADA systems using IEC 61850/Modbus TCP/IP diagnostics.
Maintenance: Perform quarterly checks of redundancy status, control mode operation, and protection settings. Inspect conformal coating for damage; clean module vents with dry compressed air to prevent overheating. Use EX2100e diagnostic tools to monitor field current, voltage regulation accuracy, and communication link integrity. Replace faulty modules with GE-approved spares (hot-swappable for minimal downtime).
Fault Diagnosis: Retrieve fault codes via EX2100e HMI (overexcitation, underexcitation, communication loss, power supply failure). Check field current/voltage sensors for calibration; verify redundant power inputs and communication cables. Inspect protection settings for compliance with generator and grid specifications.
