Allen-Bradley I/O modules

Allen-Bradley I/O modules connect programmable logic controllers (PLCs) to field devices such as sensors, switches, motors, and actuators, allowing automation systems to monitor inputs and control outputs across industrial equipment. These modules are commonly used with Allen-Bradley PLC platforms including ControlLogix, CompactLogix, and MicroLogix systems in manufacturing, material handling, packaging, and process control environments.

Allen-Bradley I/O modules are available in digital and analog configurations and support a wide range of voltages and signal types. Their modular design allows automation systems to scale easily by adding additional input or output channels, making them ideal for system expansions, machine retrofits, and replacement of legacy PLC hardware in industrial control panels.
