Key Features and Advantages
Legacy System Integration: The IC695ACC651 eliminates the need for costly rewiring by directly connecting Series 90-70 I/O terminal blocks to RX3i PCI modules. This reduces migration time by up to 40% compared to traditional rip-and-replace methods . Its dual-bus architecture ensures seamless data transfer between legacy serial protocols and modern PCI-based control systems, supporting real-time diagnostics and remote monitoring.
High-Reliability Design: Built to withstand extreme temperatures (-25°C to 60°C) and harsh conditions (dust, moisture), the adapter excels in offshore rigs, mining sites, and outdoor manufacturing environments. The IP54-rated enclosure (when installed in compatible housing) and surge protection (1.5kV isolation) ensure reliable performance in high-vibration or electrically noisy settings .
Hot-Swap Maintenance: Modules can be replaced while the system remains operational, critical for continuous-process industries like pharmaceuticals and food & beverage. The adapter’s LED indicators (PWR, STAT, COM) provide real-time status monitoring of power, module health, and communication integrity .
Scalable Configuration: The IC695ACC651 works with IC695ACC650 (9-slot) and IC695ACC652 (5-slot) conversion racks to support small to large-scale migrations. It enables up to 32,000 discrete I/O points and 4,096 analog channels, making it suitable for both retrofits and greenfield projects 7.
Applications
The GE IC695ACC651 is essential for industrial automation scenarios requiring backward compatibility with advanced control capabilities:
- Oil & Gas: Enables cost-effective upgrades of offshore platform control systems by reusing existing Series 90-70 field wiring while integrating with RX3i-based SCADA systems for real-time production optimization .
- Power Generation: Supports turbine control retrofits by connecting legacy I/O modules to modern PACSystems RX3i controllers, improving diagnostic accuracy and reducing maintenance costs .
- Manufacturing: Facilitates phased migrations of assembly line control systems, allowing parallel operation of old and new modules during transition periods without disrupting production .
- Water Treatment: Ensures uninterrupted operation of pump and valve control systems during upgrades by bridging Series 90-70 I/O with RX3i-based process automation platforms 10.

Installation and Maintenance
Installation Preparation:
- Power down the system and disconnect the target RX3i backplane.
- Align the IC695ACC651 with the conversion rack’s slot, ensuring the snap-in latches engage fully.
- Secure the module with M2.5 screws and reconnect the Series 90-70 terminal block using the included jackscrew mechanism .
- Power up the system and verify STAT LED status (solid green = normal operation).
Maintenance Recommendations:
- Conduct quarterly inspections to clean dust from vents and check for loose connections. Replace the adapter if the STAT LED blinks red (internal fault) or amber (component nearing end-of-life).
- Update firmware annually using GE’s Proficy software to address security vulnerabilities and improve protocol compatibility.
- Store spare adapters in an anti-static bag at temperatures between -20°C and 70°C to extend capacitor lifespan .
