Allen-Bradley 1771-A3B1 Key Features
Vibration-Reinforced Structure: The Allen-Bradley 1771-A3B1's 1.5mm stamped steel frame has passed IEC 60068-2-6 sinusoidal vibration testing (10-150Hz/2g) and has demonstrated zero deformation after five years of continuous operation on mining trucks.
Fanless Cooling Design: Serrated heat dissipation grooves reduce thermal resistance to 0.8°C/W, ensuring a temperature rise of ≤15°C when the Allen-Bradley 1771-A3B1 chassis is fully loaded at 70°C.
Misinsertion Protection: The module guide slots feature a built-in physical latch (patent number US4588879) to prevent the 1771-IBD digital module from being mistakenly inserted into the 1771-IAD slot.
Allen-Bradley 1771-A3B1 Application examples
Germany's maglev rail beams: The Berlin Transrapid maintenance section uses an Allen-Bradley 1771-A3B1 rack cluster (two per beam), achieving ±0.1mm accuracy in controlling the gap between electromagnetic coils in a confined space.
Alaska's oil pumping station: The Allen-Bradley 1771-A3B1 drives a 1771-OFE heating module in a -40°C environment, ensuring crude oil fluidity for over 10 years.
