1771-A4B

The 1771-A4B I/O chassis from Allen Bradley is engineered for robust performance within the PLC 5 system architecture. This configuration allows for a total of 16 slots, accommodating several modular components essential for your application. Notably, it can manage up to four I/O racks, employing 1/2-slot addressing for optimal space utilization. Installation of this chassis requires 36 keying bands made of plastic, ensuring secure setup.

Essential hardware components for installation include one cup washer, one star washer, four flat washers, and two #10 to 32 nuts with captive lock washers, all ensuring stability. This device allows for panel mounting and facilitates rear mounting, providing flexible installation options. Grounding is supported to enhance safety and performance.

Compatibility is versatile with various processors, particularly those rated between 2 and 4 amps that possess integral power supplies. Additionally, you can utilize power supply modules with ratings from 3 to 8 amps. External power supplies intended for this chassis must be rated between 6.5 and 16 amps. Furthermore, the leftmost slot is dedicated for processor module installation as well as the I/O adapter module. Communication modules and I/O modules can occupy any slot but are restricted from the leftmost slot, similar to power supply module installations. All these features combine to make the 1771-A4B an adaptable and essential component for performance-driven industrial setups.
