The Allen-Bradley 1756-IV16 is a 16-point 24V DC sinking input module engineered for the high-performance ControlLogix platform. Designed for demanding discrete automation tasks, this module captures sensor, limit switch, and pushbutton signals with robust filtering and electrical isolation. Its compact form factor allows dense I/O configurations without compromising reliability, making it ideal for manufacturing lines, process control, and material handling systems. Each input is optically isolated from the backplane, ensuring stable operation in noisy industrial environments. The 1756-IV16 is factory-tested and shipped as a genuine, new component, backed by Rockwell Automation’s quality standards.
