GE IC694PSM001-AB PSM Module
GE IC694PSM001-AB
Product Overview
The GE IC694PSM001-AB is a Power Sync and Measurement module designed for the GE PACSystems RX3i control platform. It is a specialized module for monitoring and analyzing two independent three-phase power grids.
Using digital signal processing technology, the module continuously evaluates electrical signals from both grids. It can support measurements such as RMS voltage, RMS current, power, frequency, and phase relationships. This makes it particularly useful in industrial power management and synchronization applications.

Main Features
- Monitors two independent three-phase power grids
- Measures RMS voltage and current
- Supports power and frequency measurement
- Provides phase relationship information between grids
- Designed for industrial power synchronization applications
- Integrates with the PACSystems RX3i platform
- Supports synchronization relay functionality
- Uses DSP-based signal processing for electrical measurements
The -AB revision introduced enhanced synchronization relay operation, including consideration of breaker delay and phase-shift rate when determining the appropriate synchronization condition.
System Structure
A typical PSM system is composed of the PSM module, a terminal assembly, and interface cables. External current transformers and potential transformers can be used as the input devices. The terminal assembly provides the field interface between the electrical measurement equipment and the PSM module.
This architecture separates high-voltage field connections from the controller-side module, making the system easier to integrate into industrial power monitoring installations.
Typical Applications
The IC694PSM001-AB can be used in applications such as:
- Generator synchronization
- Utility and generator power management
- Industrial power distribution
- Load shedding systems
- Power monitoring
- Demand management
- Electrical grid synchronization
- Industrial automation systems
Installation and Maintenance
Installation should be performed according to the appropriate PACSystems RX3i documentation and electrical safety procedures. The PSM terminal assembly interfaces with potentially hazardous voltages, so field wiring and commissioning should only be performed by qualified personnel.
Before installation, verify the module revision, field wiring, CT/PT configuration, and system compatibility. During maintenance, inspect connectors, interface cables, terminal connections, and diagnostic indicators for abnormal conditions.
Why Choose IC694PSM001-AB?
For legacy RX3i installations requiring dedicated power synchronization and measurement functions, the IC694PSM001-AB provides a compact solution for monitoring two three-phase grids while supplying electrical data to the control system. Its specialized measurement capabilities make it suitable for demanding industrial power applications.
