Connects up to seven serial expansion racks with aggregate capacity of 320 discrete I/O points. Enables phased system growth without controller replacement, protecting your initial investment while accommodating future production demands.

→ Efficient Power Profile
Consumes only 132mA at 5V DC, minimizing heat generation and reducing power supply sizing requirements. Lower power draw translates to improved system reliability and reduced cooling infrastructure costs.

→ Industrial Environmental Resilience
Operates reliably across 0°C to +60°C temperature range with CE, UL, and cUL compliance. Engineered to withstand electrical noise, vibration, and harsh factory floor conditions that would compromise commercial-grade components.

→ Simplified Integration & Diagnostics
Plug-and-play installation with automatic rack addressing and built-in LED status indicators. Reduces commissioning time and enables rapid troubleshooting through visual communication health monitoring.

Typical Application Scenarios

Automotive Assembly Line Expansion
A tier-1 automotive supplier needed to add 12 welding stations to their body shop without relocating the main control cabinet. The IC695LRE001 enabled a remote expansion rack 180 feet from the primary controller, eliminating the need for 2,400 feet of individual I/O wiring. Result: 60% reduction in installation costs and three-day faster commissioning.

Chemical Batch Process Distribution
A specialty chemicals manufacturer required distributed I/O across four reactor zones separated by containment walls. Using IC695LRE001 modules, they deployed expansion racks within each zone while maintaining centralized control logic. This architecture reduced hazardous area wiring by 75% and improved maintenance safety.

Water Treatment SCADA Expansion
A municipal water facility expanded treatment capacity by adding clarifier and filtration stages 500 feet from the existing control room. The IC695LRE001's 700-foot remote capability allowed direct connection without intermediate repeaters, saving $8,000 in networking equipment while maintaining 50ms scan times.

Packaging Machine Modular Design
An OEM packaging machine builder standardized on modular control cabinets for labeling, filling, and capping stations. Serial bus transmitters enable flexible machine configurations where customers can add or remove stations based on production requirements, creating a scalable product platform.

Power Substation Monitoring Network
A utility company deployed remote I/O racks at transformer bays and switchgear locations up to 600 feet from the main SCADA controller. The IC695LRE001's extended distance capability eliminated fiber optic converters, reducing per-bay costs by $3,200 while maintaining deterministic communication.

Technical Parameters & Selection Guide

Selection Criteria:

Choose the IC695LRE001 when your application requires distributed I/O beyond the main backplane's physical capacity or when remote I/O placement reduces wiring complexity. For applications requiring more than 320 discrete points or Ethernet-based distributed I/O, consider the IC695ETM001 Ethernet module with remote I/O racks. If your expansion racks are within 10 feet of the main backplane, evaluate whether direct backplane connection (IC695CHS012) offers simpler architecture.

Verify that your CPU model supports serial expansion (IC695CPU310, IC695CPU315, IC695CPE330 confirmed compatible). Calculate total I/O point requirements including 20% growth margin, and ensure your power supply can deliver 132mA per transmitter module plus expansion rack loads.

Extended Functions & Integration Options

Redundant Communication Paths: Deploy dual IC695LRE001 modules with redundant CPUs for fault-tolerant expansion communication. Automatic failover maintains I/O connectivity during transmitter or cable failures.

Mixed I/O Architecture: Combine serial expansion racks (via IC695LRE001) with Ethernet remote I/O (via IC695ETM001) in the same system. This hybrid approach optimizes cost and performance for different zones.

Third-Party I/O Integration: Use serial expansion racks to house specialty I/O modules including high-speed counters (IC695HSC308), motion controllers (IC695PMM335), and PROFIBUS masters (IC695PBM300) that require close proximity to field devices.

Diagnostic Data Logging: Configure CPU to log serial bus communication statistics (error rates, retry counts, latency) for predictive maintenance. Trending this data identifies cable degradation before failures occur.

Custom Cable Assemblies: For harsh environments or long-distance runs, specify industrial-grade RS-232 cables with triple shielding and ruggedized connectors. We can recommend certified cable suppliers for your specific installation.

Frequently Asked Questions

What is the maximum cable length for remote rack expansion using IC695LRE001?
The module supports remote backplane connections up to 700 feet (213.36 meters) using appropriate shielded RS-232 cable. For distances beyond 500 feet, use low-capacitance cable rated for industrial RS-232 applications to maintain signal integrity. Cable quality significantly impacts maximum achievable distance.

How many expansion racks can I connect to a single RX3i system?
You can connect up to seven serial expansion racks using IC695LRE001 transmitter modules, with aggregate capacity of 320 discrete I/O points across all racks. Each rack requires one transmitter module in the main backplane and one receiver module (IC695LRE002) in the expansion backplane.

Is the IC695LRE001 compatible with legacy Series 90-30 systems?
No, this module is exclusively designed for RX3i PACSystems (IC695 series). Series 90-30 systems use different expansion architecture with IC693 series modules. The backplane connectors and communication protocols are not interchangeable between these platforms.

What type of cable is required for serial bus connections?
Use shielded RS-232 serial cable rated for industrial environments. Recommended specifications: 22 AWG twisted pair, foil + braid shield, 120-ohm impedance, rated for -20°C to +80°C. GE part number IC695ACC302 provides pre-terminated cables in standard lengths.

Does the transmitter module require separate power supply?
No, the IC695LRE001 draws 132mA at 5V DC directly from the universal backplane. Ensure your backplane power supply has sufficient capacity for the transmitter module plus all installed I/O modules. A typical IC695PSD140D power supply can support multiple transmitters.

Can I hot-swap the IC695LRE001 module during system operation?
No, serial bus transmitter modules are not hot-swappable. Removing or installing the module while the system is powered will disrupt communication to all connected expansion racks and may cause I/O faults. Always power down the backplane before servicing transmitter modules.
