The Allen-Bradley 5069-ARM is an Address Reserve Module (ARM) from the Compact 5000 I/O series by Rockwell Automation, designed to reserve specific node addresses for future module installation within CompactLogix or Compact 5000 systems. This module simplifies system expansion and maintenance by maintaining network integrity even when I/O modules are temporarily removed or replaced. The 5069-ARM features a MOD power rating of 45 mA at 18–32V DC, a MOD passthrough of 9.55 A at 18–32V DC, and an SA passthrough of 9.95 A at 0–32V DC or 9.975 A at 0–240V AC (47–63 Hz), meeting ATEX/IECEx standards for industrial environments. Engineered for safety, reliability, and seamless system continuity, the Allen-Bradley 5069-ARM ensures efficient address management and uninterrupted operation in Compact 5000 I/O networks.
