Allen-Bradley 1769-ARM Bus Current Draw Module

Allen-Bradley 1769-ARM Address Reserve Module locks in a 1769 Compact I/O rack by reserving a slot on the backplane, ensuring a fixed module address map as you add future modules. This one‑width, non‑I/O module is powered from the backplane: it draws 60 mA at 5.1 V (about 0.30 W) and consumes virtually no current from 24 V supplies, with a reported heat dissipation of 0.30 W. Measuring roughly 118 mm high by 35 mm wide by 87 mm deep and weighing about 280 g, it fits in a DIN rail or panel‑mounted enclosure and occupies a single module width in the 1769 backplane. The device’s backplane power budget guidance lists a distance rating of eight modules from the power supply, and it requires compatible 1769 backplane power rails (such as PA2/PB2 or PA4/PB4) to operate within a CompactLogix system.
