Unlike standard expansion cards, the 1775-MED is engineered for superior data integrity in electrically noisy industrial environments.
Logic Capacity: 8K Words (equivalent to 16KB of core execution space)
Data Integrity: Integrated Error Correcting (ECC) logic prevents bit-flips that crash legacy PLC-3 CPUs
Bus Timing: Optimized 450ns access latency critical for maintaining backplane scan-cycle timing
Power Draw: Steady 2W from logic backplane (5V DC ±5%) - verify power supply loading when adding multiple units
Form Factor: Approximately 4.6 x 30 x 39.5 cm - full-sized rack-mount card for deep-chassis PLC-3 systems
Technical & Logistics Data
OEM Part Number: 1775-MED (also referred to as 1775MED)
Gross Weight: 3.1 kg (includes heavy-duty anti-static packaging)
Shipping Hub: Xiamen, China (Global Priority Export)
Origin: USA Design / Origin
Operating Temperature: 0°C to +60°C (designed for unconditioned factory floor cabinets)
Why MRO Engineers Choose the 1775-MED
The PLC-3 platform remains a critical workhorse in industrial automation. When memory fails, entire production cells halt, making reliable replacements essential.
Direct Swap Compatibility: No firmware flashing required - hardware-level memory expansion
Enhanced Reliability: 128K RAM layout includes dedicated parity bits for superior reliability over standard 1775-ME series
Low Standby Drain: 100μA standby current excels in systems requiring battery-backed RAM retention during scheduled shutdowns
Expedited Logistics for Critical Operations
Every hour of PLC-3 downtime costs thousands. Our supply chain is optimized for zero-friction export to minimize your production losses.
30-Minute Response: Receive formal quotes within 30-60 minutes of inquiry
Quick Turnaround: Parts in stock move out the door within 24 to 72 hours. If your line is completely down, we prioritize "emergency pulls" for same-day international shipping.
Bulletproof Packaging: Your hardware is wrapped in multi-layer protection—think vacuum-sealed ESD bags, custom shock-absorbing foam, and heavy-duty double-wall crates built for long-haul export.
Priority Global Logistics: We leverage elite-level accounts with DHL, FedEx, and Aramex. Our team handles the customs red tape for 220+ countries to ensure your order doesn't get stuck at the border.
How do you verify the integrity of a 30-year-old memory module?
Our engineering team performs Multi-Point Physical Inspection on every 1775-MED, checking for electrolytic capacitor leakage and pin oxidation. We offer Pre-Shipment Video Verification so you can see the exact unit and factory seals before shipment.
Your pricing is often 15% below market—how is this achieved?
By operating a Global Sourcing Network that scans localized surpluses worldwide and cutting out middlemen. We pass these savings directly to MRO buyers and offer Price Matching for valid lower quotes.
Will this 128K ECC RAM require a firmware flash?
No. The 1775-MED is a hardware-level expansion designed for Plug-and-Play integration with the PLC-3 backplane. The module is recognized upon power-up with compatible 16-bit word length architecture. Always verify your rack's power budget for the 2W draw.
