Product Description P/N: 1769-ARM
Description
The Allen-Bradley 1769-ARM is an address reserve module used in CompactLogix and MicroLogix 1500 systems to maintain slot addressing when a physical I/O module is removed. It provides a single-word input data file and ensures that user programs referencing the associated slot remain valid. With minimal current draw and low heat dissipation, the 1769-ARM offers a simple and reliable method for preserving system configuration integrity.

Information About 1769-ARM
The 1769-ARM is part of the Allen-Bradley 1769 Compact I/O family and functions as a placeholder module, reserving the I/O memory space of the slot it occupies. This allows the system to operate without reconfiguring the I/O map when modules are removed or replaced. It features an open-style enclosure, DIN-rail or panel mounting capability, and compatibility with 1769-series power supplies such as the 1769-PA2, 1769-PB2, 1769-PA4, and 1769-PB4. Typical usage includes maintenance staging, system testing, phased installation, or applications requiring consistent slot addressing even when no I/O module is present.
Key Features
- Address reservation: Maintains I/O slot addressing for CompactLogix and MicroLogix systems.
- 1-word input data file: No output or configuration files required.
- Low power draw: Consumes only 60 mA at 5.1 VDC.
- DIN-rail or panel mount: Flexible installation options for control panels.
- Compatible power supplies: Works with 1769-PA2, -PB2, -PA4, and -PB4 units.
- Compact, open-style design: Preserves slot spacing without adding functional I/O.
- Wide environmental tolerance: Supports operation from 32 to 140 °F (0 to 60 °C).
The 1769-ARM delivers the reliability and precision required for addressing stability in modular Compact I/O systems.
