The Allen-Bradley 1756-IH16I Discrete Input Module is a digital input interface used to read on/off signals from field devices and convey them to a programmable logic controller. With the 1756-IH16I designation, this module serves as a dedicated input block within industrial automation systems for reliable sensing of discrete signals. It enables operators to monitor sensors and switches and integrates with standard Allen-Bradley control platforms to support deterministic input processing and timely control decisions.
