Product Description
The IS220PDIOH1B is a robust discrete I/O module designed as part of the Mark VIe control system family for turbine and industrial process control applications. It serves as an interface module that accepts a large number of discrete field signals (digital switch or relay type) and provides discrete outputs through relay or contact circuits, all while integrating into the control rack network via dual Ethernet ports.
This module includes a local processor and data‑acquisition board which handles signal processing and communication tasks. The dual Ethernet ports enable redundancy or separation of control and monitoring networks, enhancing system reliability. The module supports simplex, dual, and triple‑redundancy (TMR) configurations when used with appropriate terminal boards.
Its form‑factor (compact size and light weight) ensures easy installation and replacement in control racks, and the industrial‑grade design allows use in harsh environments (wide temperature range, vibration, hazardous area compliance). It is suited for applications where reliable, deterministic discrete input/output handling is required for critical control systems.
Applications
-
Gas turbine control systems: monitoring and controlling discrete status signals (e.g., fuel valve status, ignition switch, auxiliary equipment start/stop).
-
Steam turbine control systems: discrete I/O for valve actuations, interlocks, trip logic and auxiliary device control.
-
Wind turbine or other renewable energy control systems where discrete I/O modules integrate into the control network.
-
Industrial process automation systems requiring high‑integrity discrete I/O handling, especially in hazardous environments.
-
Upgrades or spare replacement modules for existing Mark VIe control racks to extend system life or enhance redundancy capability.
Advantages
-
High reliability – Built for critical control systems with redundant communication ports and compatibility with simplex/dual/TMR configurations.
-
Compact form factor & lightweight – Easier installation or retrofit in tight control rack environments (approx. 0.91 kg weight).
-
Network‑ready with dual Ethernet ports – Enables robust network architecture, redundancy and faster communication.
-
Wide environmental tolerance – Operates from about ‑30 °C to +65 °C, suitable for tough industrial applications.
-
Large discrete I/O capacity – Handles up to 24 inputs / 12 outputs (depending on configuration), offering flexibility in discrete signal management.
-
Hazardous location certification – When used with correct terminal boards, suitable for Class I Division 2 and ATEX Zone 2 environments.
-
Modular design – Plug‑in I/O pack module facilitates maintenance and replacement, reducing system downtime.
-
Integration friendly – Designed to integrate with the larger Mark VIe system ecosystem, supporting existing control infrastructure and extending lifecycle.
