The Allen-Bradley 1771-DR Input/Output logic controller is designed for high-speed industrial applications such as presence sensing, canning, bottling, and packaging. It excels in tracking and responding to high-speed events independently of the host processor's scan time, making it ideal for material sorting on conveyors. The module handles up to eight discrete inputs and controls four discrete outputs, with input pulses programmable between 50 microseconds to 10 milliseconds and an output response time of under 1 millisecond. It features a robust range of input and output voltage specifications and supports high operational temperatures, ensuring reliable performance across various conditions. Additionally, the module includes four 3A rectifier fuses for each output, providing effective circuit protection.
