The IS220PAOCH1B is an Analog Output Pack designed for high-reliability industrial control systems. It belongs to the Mark VIe I/O Pack Series, which provides modular input/output connectivity for distributed control and turbine management systems.
This module converts digital control signals from the system controller into precise analog outputs, such as 0–10 V or 4–20 mA current loops, used to drive actuators, valves, and process-control devices. Built to operate in harsh industrial environments, it provides excellent isolation, diagnostic feedback, and long-term stability.
Its design emphasizes easy maintenance, compact form factor, and hot-swappable capability, making it ideal for continuous process industries that require high system uptime and quick field replacement.
