Description: Allen-Bradley 1771-A4B is a general purpose I/O chassis. This hardware is a sixteen (16) slot chassis that provides a backplane connection and houses the 1771 PLC module. It offers A maximum backplane current of 24 A and is designed for panel mounting. Its total weight is 7.3 kilograms or 16 pounds.

A universal I/O chassis is a device used to house and connect various input/output modules. It usually includes one or more slots for mounting input/output modules and providing a power supply and communication interface.

A general purpose I/O chassis is generally highly flexible and scalable, as it can accommodate different types and specifications of input/output modules to meet different application requirements.

The 1771-A4B is capable of receiving power through the 1771 processor, which has an integrated power supply providing 2-4 amps, a power module rated for 3-8 amps, and an external power supply with an output current of 6.5-16 amps. As a general rule, do not install external power supplies and power modules on the 1771-A4B. This power connection is incompatible and will cancel the hardware configuration.

General purpose I/O enclosures can be used for a variety of applications, such as industrial automation, smart homes, medical devices, and more. In these applications, the universal I/O chassis can be used to connect various input/output devices, such as sensors, actuators, motors, lamps, etc., for automation and intelligent control.

General-purpose I/O enclosures are generally highly reliable and stable, and are easy to install and configure. It can be managed and monitored through network management software to ensure the normal operation of the system.
