Allen-Bradley 1771-A1B Key Features
Reinforced Electrical Isolation
The Allen-Bradley 1771-A1B features a triple insulation design, effectively blocking ground loop interference and ensuring signal purity for sensitive analog modules within the inverter cabinet.
Wide Temperature Range
With an operating range of -40°C to 85°C, this backplane can be deployed directly in open-air valve stations on the Alaskan oil pipeline, eliminating the need for a thermostat.
Patented Mechanical Vibration Resistance
With its V-shaped slot and dual DIN rail locking, the Allen-Bradley 1771-A1B maintains reliable connection even in the vibration environment of mine crushers.
