Product Introduction
The IS220PAICH2A is an analog input/output (I/O) pack module designed for the Mark VIe distributed control system platform. It functions as the interface between the Ethernet-based I/O network of the control rack and the analog terminal board carrying process signals (such as temperature, pressure, flow, current loops).
This module offers both analog input channels and analog output loops, providing flexibility in monitoring and controlling continuous process variables. It is engineered for use in high-end industrial automation, power generation, turbine control, and other critical process plants. The module supports dual Ethernet ports for redundant I/O network connections, making it suitable for systems requiring high availability and reliability.
Because of its modular plug-in design, the IS220PAICH2A allows service technicians to install, replace or upgrade analog I/O easily, and the integration into the Mark VIe I/O rack ensures consistent performance, compatibility with other modules, and streamlined maintenance.

In power generation plants (gas, steam), the module monitors analog sensors (such as temperature thermocouples, 4-20 mA transmitters) and drives analog control loops for valves and actuators.
-
In chemical or petrochemical process plants, it handles analog process variables like flow, level, and pressure, feeding data into the central control system so that corrective control actions can be taken.
-
In turbine control systems, the module forms part of the I/O rack that interfaces the control network to field analog devices, enabling closed-loop control, monitoring and redundancy.
-
In manufacturing automation, it can be used where high-density analog I/O is needed and the control architecture demands modular, reliable hardware with diagnostic capability.
-
In retrofit or modernization projects, the IS220PAICH2A allows integrators to upgrade or expand analog I/O capability without replacing entire control cabinets, thereby saving cost and time.
