1775-AC

The Allen Bradley 1775-AC is classified as a PLC expansion chassis, providing critical support for increasing I/O capabilities in various automation tasks. It accommodates six dedicated I/O module slots, allowing users to expand their PLC infrastructure efficiently. In addition, this unit can connect with up to four additional chassis, thereby significantly enhancing the overall system's scalability and flexibility.

The chassis is built to withstand operational conditions defined by a humidity tolerance of 5% to 95%, ensuring reliability in diverse environments. Designed for temperature resilience, it operates effectively in ambient conditions between 0 and 60°C and can endure storage temperatures as high as 85°C. This allows the unit to function in a range of industrial conditions.

To facilitate user interaction, the chassis incorporates a front panel keypad for inputs and feedback on system status is provided through LED indicators. The interface features a standard 25-pin parallel output type, enhancing compatibility with other components. Mounting options offer versatility, as the chassis can be attached to a 9-inch rack or directly to a panel, making installation straightforward.

Electrical specifications include an input voltage requirement of 5 V and a maximum backplane current of 5.0 A, which are critical for ensuring optimal performance. The 1775-AC chassis is an integral component designed to adapt and grow within a PLC system, providing the necessary infrastructure for advanced process control.
