Product Introduction
The IS220PAICH1B is an Analog Input/Output Pack module designed for use within the Mark VIe distributed control system family. It functions as a high-performance analog I/O interface, converting analog signals from field sensors and transmitters (such as 4-20 mA loops, voltage inputs) into digital form for the control system, and providing analog output capability for control loops.
This module is engineered for process automation, power generation, turbine control, and other industrial automation applications where analog sensor data is critical. The pack features configurable input ranges, selectable output options, diagnostic indicators, and dual-Ethernet communication links, making it suitable for high-availability systems.
As part of the modular I/O rack architecture of Mark VIe systems, the IS220PAICH1B allows straightforward installation, replacement and integration, supporting both new builds and retrofits of analog I/O capabilities.

Applications
The IS220PAICH1B module is suited for a variety of industrial applications where analog signal management is required:
-
In power generation plants (gas, steam turbines), it monitors analog signals such as temperature sensors, flow transmitters, pressure loops and provides analog outputs for valve control and actuator commanding.
-
In petrochemical, refining or chemical-process facilities, the module handles analog signal acquisition and control loop outputs for process variables such as level, concentration, temperature, or differential pressure.
-
In automated manufacturing or process industries, the module is integrated into I/O racks for large-scale analog monitoring and control, enabling system modularity and servicing ease.
-
In plant retrofits, when upgrading analog measurement and control capabilities, the IS220PAICH1B allows reuse of existing racks and networks while enhancing analog I/O performance.
-
In distributed control networks requiring redundancy and diagnostics, this module contributes to system reliability and maintainability by offering dual-Ethernet links and status monitoring.
Advantages
Choosing the IS220PAICH1B yields several strong benefits:
-
High flexibility: The ability to configure multiple input types (voltage or current) and two analog outputs means the module covers a wide range of analog sensor and actuator use-cases.
-
Compact size and moderate weight: With an approximate size of 13.3 × 7.08 × 3.93 cm and weight about 1.0 kg, the module is space-efficient in control racks.
-
Rugged industrial design: The wide operating temperature range (–40 °C to +85 °C) supports demanding environmental conditions. The module’s certification for hazardous areas (Zone 2 / Group IIC) further enhances suitability.
-
Redundant network support: Dual Ethernet ports allow redundant network paths, improving system availability and failure tolerance.
-
Maintenance and diagnostics friendliness: LED indicators provide visual health/diagnostics; plug-in design allows quick replacement; compatibility with Mark VIe rack system simplifies servicing and upgrades.
-
Investment protection: Belonging to the established IS220 family and Mark VIe architecture, the module ensures compatibility with broad I/O ecosystem, facilitating long-term support and scalability.
-
Versatile signal handling: With both input and output analog channels, the module supports both measurement and actuation tasks in one unit, reducing the number of separate modules needed.
