Compatible Replacement & Equivalent Models
The following models are commonly evaluated as direct or functional replacements for the 1769-L30ERM. Always verify firmware, I/O compatibility, and motion axis requirements before substitution.
- 1769-L30ER — CompactLogix 1MB, EtherNet/IP, no motion (discrete only); suitable if motion axes are not required
- 1769-L30ERMS — Safety variant with integrated SIL 2 / PLd safety functions; drop-in for safety-critical applications
- 1769-L33ERM — 2MB memory upgrade; recommended when program size exceeds 1MB
- 1769-L36ERM — 3MB memory, higher I/O density; for larger system expansions
- 1769-L19ERM — Compact form factor, 512KB; suitable for smaller motion applications
- 5069-L306ERM (CompactLogix 5380) — Next-generation platform; higher throughput, dual Gigabit EtherNet/IP; recommended for new designs
- 5069-L310ERM (CompactLogix 5380) — 10MB, up to 31 axes; for complex multi-axis motion systems
Note: Cross-platform migration (5370 → 5380) requires project conversion in Studio 5000 and hardware re-wiring. Consult Rockwell’s migration guide or contact Konmask for assistance.

- Network: EtherNet/IP (DLR, linear, star topologies)
- Power Supply: 1769-PA2 (120/240 VAC), 1769-PB2 (24 VDC)
- Chassis: No dedicated chassis required — modular rail-mount design
Selection Guide
Use the following criteria to select the correct CompactLogix controller for your application:
- Motion axes needed ≤ 16, memory ≤ 1MB: → 1769-L30ERM ✓ (this model)
- Motion axes needed ≤ 16, memory 1–2MB: → 1769-L33ERM
- Motion axes needed ≤ 16, memory 2–3MB: → 1769-L36ERM
- No motion required, 1MB: → 1769-L30ER
- Safety (SIL 2 / PLd) required: → 1769-L30ERMS
- New design, higher performance: → 5069-L306ERM or 5069-L310ERM (CompactLogix 5380)
- Compact / low-axis application: → 1769-L19ERM
If you are unsure which model fits your system, contact Konmask’s technical team with your axis count, I/O requirements, and existing network topology.

Replacement & Compatibility FAQ
Q: Can I replace a 1769-L30ERM with a 1769-L30ER?
A: Only if your application does not use CIP Motion. The L30ER lacks motion control capability.
Q: Is the 1769-L30ERM compatible with CompactLogix 5380 (5069) I/O?
A: No. The 5370 series uses 1769 Compact I/O; the 5380 series uses 5069 Compact I/O. They are not interchangeable.
Q: What firmware version does the 1769-L30ERM require?
A: Minimum v20; latest recommended firmware is available via Rockwell’s Product Compatibility and Download Center (PCDC).
Q: Can Konmask assist with migration from 1769-L30ERM to CompactLogix 5380?
A: Yes. Contact our technical team for a migration assessment and Studio 5000 project conversion support.
Q: Do you offer exchange / core return programs?
A: Yes, for refurbished units. Contact us for details on core return credit.
