Features:
- Supports 24 discrete input channels for efficient signal acquisition in distributed control systems.
- Provides optical isolation up to 150 V on all inputs to enhance system stability and protection.
- Includes a 4 ms hardware filter to improve input signal quality and reduce interference.
General Electric IS220PDIAH1A is widely applied in Mark VIe control systems for collecting discrete field signals from industrial processes. With 24 input channels and 28 Vdc operating power, it provides reliable data acquisition for turbine control, process automation, and monitoring systems. Its architecture supports integration with dedicated terminal boards for flexible system design.
The IS220PDIAH1A enhances signal integrity through optical isolation up to 150 V across all inputs. This feature ensures separation between field wiring and internal electronics, reducing the impact of electrical noise and voltage disturbances. Combined with a 4 ms hardware filter, the module delivers stable input recognition in fast-changing industrial environments.
Designed for demanding operational conditions, General Electric IS220PDIAH1A operates across a wide temperature range from -30 to + 65°C (-22 to + 149°F). It also supports AC voltage rejection capability up to 60 V rms at 50/60 Hz, making it suitable for power generation and heavy industrial applications. Its compatibility with multiple terminal boards further expands deployment flexibility in Mark VIe architectures.
The IS220PDIAH1A General Electric Discrete I/O Pack may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Physical Interface Connection: The module has a built-in DC-37 pin connector on the bottom, which can be directly inserted into a compatible discrete input terminal block (such as TBCIH1).
- Network Redundancy Connection: The module is equipped with two 100 Mbps Ethernet RJ45 interfaces on the top for connecting to the Mark VIe control system's IONet single/dual/triple redundancy network.
- Field Contact Connection: External dry contacts are connected via the terminal block, with the module providing a 32 VDC wetting voltage to keep the contacts clean.
- Power Input Connection: No separate wiring is required; the system's operating power is directly input and distributed through the network cable (PoE) or the connected terminal block interface.
- Gas Turbine Monitoring: Widely used for acquiring switch signals in the main auxiliary systems and control panels of GE heavy-duty gas turbines (such as the 9FA/7FA series).
- Steam Turbine ETS System: Often used as the core acquisition unit of the Emergency Trip System (ETS), capturing critical safety protection trigger signals such as overspeed and low oil pressure.
- Power Plant Auxiliary Workshops: Suitable for valve limit and circuit breaker status monitoring in peripheral processes such as power plant water treatment, coal conveying systems, and dust removal.
- Heavy Industry Electrical Cabinets: Deployed in high-reliability cabinets in continuous industrial sites such as steel and petrochemical plants for large-scale centralized isolated digital signal reading.
- Remote Firmware Upgrade: Supports online remote download and update of the flash firmware within the I/O package via the ControlST software tool of the Mark VIe system.
- Self-Diagnostic Logic: The firmware incorporates advanced diagnostic algorithms to monitor internal voltage, temperature, channel status, and network communication health in real time.
- Sequence Event Logging: Built-in SOE (Sequence of Events) firmware algorithm captures and records input state transition times with a resolution of 1 millisecond.
- Code Execution Control: The firmware runs on a dedicated real-time operating system and features optimized digital filtering and anti-jitter logic for discrete input signals.
