Industrial Control Power Solution — Allen-Bradley 1770-XYC | PLC-5 Series
Where This Product Is Used
The Allen-Bradley 1770-XYC is the OEM-specified lithium battery module for the Rockwell Automation PLC-5 programmable logic controller family. It is deployed across a wide range of mission-critical industrial environments where uninterrupted CMOS RAM backup is essential:
- Automotive Manufacturing — Body-in-white welding lines, paint shop conveyors, and powertrain assembly cells running PLC-5/10, 5/15, 5/20, 5/25, 5/30, 5/40, and 5/60 processors.
- Oil & Gas Processing — Upstream wellhead RTU panels and downstream refinery DCS integration nodes where program loss during power interruption is unacceptable.
- Water & Wastewater Treatment — SCADA-linked pump station controllers and chemical dosing systems requiring 24/7 uptime with infrequent maintenance windows.
- Pulp & Paper Mills — Continuous process lines (digesters, bleach plants, paper machines) where a controller restart causes costly production loss.
- Food & Beverage — CIP-intensive packaging lines and batch process controllers subject to frequent power cycling during sanitation shutdowns.
- Mining & Minerals — Conveyor drive control panels and crusher automation systems in remote sites with limited spare-parts logistics.
- Semiconductor Fab — Cleanroom HVAC and process gas control panels requiring validated, traceable replacement components.

Why Engineers Specify This Model
- Zero-reprogram guarantee — A healthy 1770-XYC ensures the PLC-5 processor retains its full program image across planned and unplanned power outages, eliminating costly re-download and recommission cycles.
- Early-warning diagnostics — The processor’s built-in BAT status bit (S:11/14) provides advance notice before battery failure, enabling planned replacement during scheduled maintenance windows rather than emergency shutdowns.
- Drop-in replacement — Identical form, fit, and function to the original factory-installed battery; no firmware changes, no configuration edits, no tools required beyond a flat-blade screwdriver.
- Long shelf life — Lithium chemistry retains >90% capacity after 5 years of storage, making it suitable for strategic spare-parts inventory.
- Broad processor compatibility — A single SKU covers the entire PLC-5 family, simplifying procurement and reducing storeroom SKU proliferation.

Application-Specific FAQ
Q: How do I know when the 1770-XYC battery needs replacement?
A: Monitor the PLC-5 processor status file word S:11, bit 14 (BAT). When this bit goes HIGH, the battery voltage has dropped below the safe threshold. RSLogix 5 will also display a “Low Battery” fault in the controller diagnostics panel. Replace the battery within 30 days of the first warning to avoid data loss.
Q: Can I replace the battery while the PLC-5 is powered on (hot-swap)?
A: Yes — the PLC-5 processor maintains RAM from the backplane power supply while the battery is disconnected, provided the swap is completed in under 30 seconds. Always back up the program to a PC via RSLogix 5 before performing any battery replacement as a precaution.
Q: Is the 1770-XYC compatible with the PLC-5/250 and PLC-5/VME processors?
A: The 1770-XYC is specified for the standard PLC-5 rack-mount family. The PLC-5/250 and VME variants use different battery specifications — contact our technical team to confirm the correct part number for those platforms.
Q: What is the recommended replacement interval for preventive maintenance programs?
A: Rockwell Automation recommends replacing the 1770-XYC every 3 years in standard industrial environments (0–40 °C ambient). In high-temperature enclosures (>50 °C), annual replacement is advisable. Align battery replacement with your annual planned shutdown schedule.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. A CoC is available for every order upon request. Please note your requirement in the order comments or email support@konmask.com after purchase.
