The 1756-IN16 ALLEN-BRADLEY is a high-performance digital input module designed for the ControlLogix platform, offering 16 individually isolated channels for reliable field device monitoring. Each input accepts 24V DC signals and provides electronic short-circuit protection, ensuring robust operation in demanding automation applications. The module features a sinking or sourcing configuration via the backplane, with an input delay of 1 ms to 25 ms (selectable via software) to filter electrical noise. Its compact form factor fits seamlessly into standard 1756 chassis, while the hot-swappable design allows replacement without system shutdown. The module is fully compatible with Rockwell Automation's Studio 5000 Logix Designer environment for easy configuration and diagnostics.
