The IS220PDIAH1B is a discrete input I/O module designed for industrial automation and turbine control systems.
It is part of the IS220 family used in modular I/O racks for capturing discrete (on/off) signals from field devices such as switches, sensors, and trip contacts.
This module is engineered to provide high reliability in harsh industrial environments, including power generation, process control, and turbine systems.
The IS220PDIAH1B supports network redundancy, has hazardous-location approvals, and can withstand wide temperature ranges.
Its primary role is to translate real-world discrete inputs into signals the control system can process safely and accurately.
