Compatible Replacement & Equivalent Models
When the IC695LRE001B is unavailable or end-of-life, the following models may serve as functional replacements or equivalents depending on system configuration:
- IC695LRE001 — Earlier revision of the same module; functionally equivalent in most RX3i applications. Verify firmware compatibility before substitution.
- IC695LRE001C — Later revision with potential firmware enhancements; backward compatible with RX3i backplanes.
- IC694LRE001 — Series 90-30 equivalent for legacy RX3i-to-Series 90-30 mixed architectures; not a direct drop-in replacement.
- IC695RMX128 — RX3i Remote I/O Scanner; alternative approach for distributed I/O using PROFINET instead of serial bus — requires system redesign.
- Third-party serial bus transmitters — Not recommended; GE RX3i serial bus is proprietary. Only GE-certified modules ensure protocol compliance.
⚠ Always verify hardware revision, firmware version, and backplane slot compatibility before substituting any module. Contact Konmask for pre-sale technical validation.
Why Choose the Original Model
- Guaranteed Protocol Compliance: The IC695LRE001B is engineered exclusively for the GE RX3i Serial Expansion Bus — no third-party module can replicate its proprietary timing and handshake protocols.
- Seamless Integration: Plug-and-play with all RX3i CPUs (IC695CPE302, IC695CPE305, IC695CPE310, IC695CPE400) without additional configuration.
- Proven Reliability: Designed for 24/7 industrial operation with full EMI/EMC shielding and vibration resistance per IEC 61131-2.
- Vendor Support: Emerson (formerly GE Intelligent Platforms) provides full lifecycle support, firmware updates, and replacement parts.
- Reduced Commissioning Risk: Using the original module eliminates compatibility unknowns and reduces system validation time.
Typical Applications
- Remote I/O expansion in PACSystems RX3i distributed control architectures
- Oil & gas pipeline monitoring and SCADA systems
- Power generation and substation automation
- Water/wastewater treatment plant control
- Automotive and discrete manufacturing assembly lines
- Chemical processing and batch control systems
- Building automation and HVAC control panels
System Compatibility
The IC695LRE001B is compatible with the following GE PACSystems RX3i components:
- CPUs: IC695CPE302, IC695CPE305, IC695CPE310, IC695CPE400, IC695CPE410
- Backplanes: IC695CHS007 (7-slot), IC695CHS012 (12-slot), IC695CHS016 (16-slot)
- Power Supplies: IC695PSA040, IC695PSD040, IC695PSA140

- Programming Software: Proficy Machine Edition 8.x and above
- Not compatible with: Series 90-70, VersaMax, or PACSystems RSTi-EP without additional interface hardware
Selection Guide
Use the following criteria to determine if the IC695LRE001B is the correct module for your application:
- Step 1 — Confirm Architecture: Is your system a PACSystems RX3i? If yes, proceed. If Series 90-30 or 90-70, consult IC694LRE001 or IC697LRE001 respectively.
- Step 2 — Identify Expansion Need: Do you need to expand I/O beyond the local backplane via serial bus? If yes, IC695LRE001B is the transmitter module required on the CPU rack.
- Step 3 — Count Expansion Racks: Each IC695LRE001B supports one serial bus segment. Multiple remote racks may require additional transmitter/receiver pairs.
- Step 4 — Check Slot Availability: Confirm an available single-width slot in your RX3i backplane.
- Step 5 — Verify Firmware: Ensure your CPU firmware supports the IC695LRE001B revision (B). Check GFK-2314 for version compatibility matrix.
- Step 6 — Distance Requirement: Serial bus supports up to 100 meters between transmitter and receiver. For longer distances, consider PROFINET-based remote I/O (IC695RMX128).

Replacement & Compatibility FAQ
Q: Can IC695LRE001 (revision A) replace IC695LRE001B (revision B)?
A: In most cases yes, but verify firmware compatibility. Revision B may include bug fixes or enhanced diagnostics not present in revision A. Contact us for a pre-sale compatibility check.
Q: Is the IC695LRE001B compatible with PACSystems RX3i CPE400?
A: Yes. The IC695CPE400 supports the RX3i Serial Expansion Bus and is fully compatible with the IC695LRE001B.
Q: Can I use a third-party serial bus transmitter in place of IC695LRE001B?

Q: What is the maximum cable length between IC695LRE001B and the remote receiver?
A: Up to 100 meters using the specified GE serial bus cable. Exceeding this distance requires PROFINET-based remote I/O.
Q: Do you supply new, refurbished, or used units?
A: We supply new, factory-surplus (unused), and certified-refurbished units. Condition is clearly stated on each listing. All units are tested before shipment.
