The IS220PDIOH1A is a Mark VIe discrete I/O pack that provides the electrical interface between one or two Ethernet networks and a discrete I/O terminal board. The pack contains a common processor board and a basic I/O board specific to the discrete input and output functions, supporting 24 contact inputs and up to 12 relay outputs.
Redundant IONet Ports
On-board Processor Diagnostics
24 Contact Input Channels
This module features two 10/100 Ethernet ports for connectivity to the IONet, supporting simplex, dual, or triple redundant control configurations. It executes a high-speed internal processor for logic, provides extensive self-diagnostics, and maintains a wide operating temperature range from -30 to 65 °C (-22 to 149 °F).

Power Generation
The module provides a reliable interface for turbine control and generator protection systems. It handles critical contact inputs for sequence-of-events recording and operates in simplex, dual, or TMR configurations.
Oil and Gas
Used for controlling distributed discrete I/O in compression stations and upstream processing facilities. The wide operating temperature range from -30 to 65 °C ensures stability in harsh outdoor industrial environments.
Combined Cycle
Integrates with the IONet to coordinate discrete signals between gas turbines, steam turbines, and heat recovery generators. It provides high-speed data exchange for seamless plant-wide control and diagnostics.
Marine Propulsion
Applied in shipboard control systems for monitoring discrete status and driving relay outputs for auxiliary machinery. The dual 10/100 Ethernet ports provide the redundant network connectivity required for maritime safety standards.
Chemical Processing
Manages high-density contact inputs and relay outputs for batch process automation and interlock logic. The on-board processor executes local diagnostics to identify field wiring faults and hardware status in real-time.
Mining and Metals
Controls heavy-duty discrete equipment in ore processing and smelting operations through a 37-pin terminal board connection. It supports 24 V dc or 125 V dc excitation for various field contact requirements.
The IS220PDIOH1A discrete I/O pack is designed to mount directly onto a compatible Mark VIe terminal board via a high-density 37-pin connector, secured by two captive mounting screws that also establish the necessary chassis ground connection.
When installing the pack, ensuring a firm mechanical seat is critical to maintain electrical integrity across the 28.0 V dc power pins and the discrete signal paths. The module draws its operating power through the terminal board and utilizes an internal electronic ID PROM to store hardware revision and serial number data, which is automatically queried by the controller upon startup for system configuration and tracking.
Proper cabling of the two 10/100 Ethernet ports (ENET1 and ENET2) is required for redundant IONet communication, and the module’s health should be monitored through the front-panel LEDs, specifically the Status indicator which signals the execution of internal self-diagnostics. Maintenance personnel must observe the specified operating temperature limits of -30 to 65 °C and should verify the excitation voltage requirements, typically 24 V dc or 125 V dc, as defined by the specific terminal board coupled with the pack.
What is the primary function of the IS220PDIOH1A discrete I/O pack?
The IS220PDIOH1A is a Mark VIe discrete I/O pack that provides the electrical interface between one or two Ethernet networks and a discrete I/O terminal board. It handles 24 contact inputs and 8 relay outputs or 24 contact inputs and 12 relay outputs depending on the terminal board.
How many Ethernet ports does the IS220PDIOH1A feature for system connectivity?
The IS220PDIOH1A pack contains two 10/100 Ethernet ports (ENET1 and ENET2) that connect to the IONet, allowing for redundant communication within the Mark VIe control system.
What types of diagnostics are available on the IS220PDIOH1A module?
The pack features extensive diagnostics including power supply monitoring, internal temperature sensing, and electronic ID (standard ID PROM) for tracking hardware revision and serial number. It also monitors the status of each I/O point.
Which terminal boards are compatible with the IS220PDIOH1A pack?
The IS220PDIOH1A is compatible with several terminal boards, including the TBCIH1, TBCIH2 (contact input) and the TRLYH1, TRLYH2 (relay output) boards, supporting simplex or redundant configurations.
What do the front panel LEDs on the IS220PDIOH1A indicate?
The LEDs include "Power" for input power status, "Status" for the overall pack health, and "Link/Act" for the Ethernet ports to show network activity and connection status.
