Description
1. Product Title
GE ACC-5595-208 – 3500 System Internal Termination Panel
2. Product Overview
The ACC-5595-208 is a specialized internal termination panel (ITP) designed for the 3500 Series Machinery Protection System. Its primary function is to provide a secure, organized, and electrically stable interface for field wiring to connect directly to the 3500 rack’s I/O modules. The ACC-5595-208 is essential for routing vibration, position, and speed sensor signals into the monitoring system for processing.
In critical machinery monitoring, signal interference or loose connections can lead to false alarms or, worse, a failure to trip during a genuine mechanical fault. The ACC-5595-208 solves this by providing high-quality screw-terminal connections and integrated shielding paths. This ensures that sensitive low-voltage signals from proximity probes and accelerometers are protected from electromagnetic interference (EMI), maintaining the high data integrity required for API 670-compliant machinery protection.

4. Key Features & Benefits
- Enhanced Signal Integrity: The ACC-5595-208 features dedicated ground and shield points for every channel. This minimizes cross-talk and ambient noise, which is critical when monitoring high-frequency vibrations in power plant environments.
- Reduced Installation Complexity: By providing a standardized termination layout, this panel simplifies the wiring process for field technicians. Clear labeling reduces the risk of wiring errors during initial commissioning or system upgrades.
- Rugged Construction: Designed to match the lifespan of the 3500 rack, the ACC-5595-208 is built to withstand the vibration and thermal cycling common in industrial motor control centers and turbine halls.
- Space Efficiency: As an internal termination panel, it mounts directly to the back of the 3500 rack, eliminating the need for external bulkhead panels and reducing the total cabinet space required.
5. Application Scenarios
- Steam Turbine Protection: Terminating signals from XY proximity probes and Keyphasor® sensors to ensure accurate radial vibration and phase monitoring for large utility turbines.
- Centrifugal Compressor Monitoring: Providing the interface for thrust position and casing vibration sensors to protect high-speed compressors in LNG or chemical facilities.
- Critical Pump Stations: Housing the terminations for accelerometers on large boiler feed pumps, where early detection of bearing wear is vital to preventing unplanned outages.
6. Frequently Asked Questions (FAQ)
- Q: What is the primary function of the ACC-5595-208?
- A: The ACC-5595-208 is an internal termination panel used to connect field sensor wiring to the I/O modules within a Bently Nevada 3500 rack.
- Q: Is the ACC-5595-208 compatible with all 3500 modules?
- A: It is designed for specific 3500 I/O configurations. While many 3500 monitors use standard ITPs, you should verify the part number against the specific I/O module (e.g., 3500/42M or 3500/40M) to ensure a correct fit.
- Q: Does it support external termination?
- A: No, the ACC-5595-208 is an internal panel. If your application requires wiring to be landed outside the 3500 rack, an External Termination Block (ETW) and a multi-conductor cable would be required instead.
