The Allen-Bradley 1771-IVN is a low true input module that operates within a voltage range of 10 to 30 VDC. This module is part of the Allen-Bradley 1771 series, which is designed for use with PLC-5 programmable logic controllers. Introduced by Rockwell Automation, the 1771-IVN is engineered to accept on/off signals from a variety of input devices such as switches, push buttons, and proximity sensors. The primary function of this input module is to process these input signals and relay them to the PLC for operations or processes that require automation. Industries employing the 1771-IVN include manufacturing, food and beverage, oil and gas, and automotive. Unique features include the ability to handle low true input logic, which provides enhanced noise immunity and allows for signals to be processed even in potentially noisy environments. Additionally, it offers high reliability and ease of integration into existing control systems, making it a preferred choice for many industrial applications.
