GE’s own Mark VIe guide describes PDIA as a discrete-input I/O pack containing a common processor board and a discrete-input acquisition board.

Product Introduction

The GE IS220PDIAH1A mounts directly to a compatible Mark VIe discrete-input terminal board and forms the active electronics layer between field contact signals and the control network. It accepts as many as 24 discrete inputs, while its dual Ethernet interfaces support simplex, redundant, or TMR network arrangements.

For a brownfield turbine, the exact terminal-board pairing is a controlled compatibility item. GE’s hazardous-location documentation specifically approves the IS220PDIAH1A with IS200STCIH1A, IS200STCIH2A, IS200STCIH8A, IS200TBCIH2C, and IS200TBCIH4C. The PDIA therefore should not be treated as a generic 24-point digital input card (the terminal board determines important electrical characteristics and certification scope).

Core Technical Specifications

The 27.4–28.6 VDC electrical window and 0.17 A maximum current are taken from GE’s Mark VIe equipment instructions. The 24-input capacity, dual Ethernet ports, DC-37 field connection, and processor/acquisition-board architecture are documented in the Mark VIe system guide.

Global Compliance & Industry Certifications

The has documented hazardous-location certification, but the certification applies to defined equipment combinations and installation conditions.

• CE Mark: Verify the applicable Mark VIe Declaration of Conformity for the exact hardware and terminal-board configuration.
• UL/cUL: Do not record standalone UL/cUL status for the loose I/O pack unless the applicable GE certification file explicitly covers it.
• ATEX: GE documentation identifies the with specified STCI/TBCI terminal boards for hazardous-location use. The certification documentation references UL DEMKO 12 ATEX 1114875X for the Mark VIe equipment family.
• IECEx: Applicable Mark VIe hazardous-location documentation should be checked for the exact hardware revision and terminal-board pairing.
• Hazardous Location: Current GE documentation covers applications including Class I, Division 2 and Zone 2 configurations. Certification is conditional on the approved assembly and installation method.
• Marine / DNV: No standalone DNV approval was established for this exact PDIA pack.
• Functional Safety: Standard is not the Mark VIeS safety discrete-input pack. GE lists IS220YDIAS1A separately for safety applications.

The hazardous-area approval is particularly important. The Class I Division 2 / Zone 2 certification framework addresses equipment intended for locations where explosive gas atmospheres may occur under defined abnormal conditions; using an unapproved terminal-board combination can invalidate that protection basis.

Verify specific lot certifications with OEM.

Long-Term Storage & Asset Preservation Guide

Keep the PDIA inside its original ESD shielding bag. The dual RJ-45 connectors, DC-37 interface, power connector, and populated electronics should remain protected from conductive dust and mechanical damage throughout storage.

Keep warehouse humidity below 60% RH where practical. This is a preservation target, not the maximum operating specification. Stable, dry storage reduces oxidation at connector contacts and helps prevent intermittent communication faults after years on the shelf.

Protect the DC-37 interface and mounting area. Never store the pack resting on its connector face. Use perimeter cushioning, keeping direct packing pressure away from connector bodies and threaded mounting points.

Record the terminal-board compatibility with the spare. The exact STCI/TBCI pairing affects electrical configuration and hazardous-location certification. Keep that relationship in the warehouse record (do not issue the pack as a generic Mark VIe digital-input replacement).

Physical Installation Prerequisites

The is an I/O pack mounted directly to a discrete-input terminal board. It is not a conventional rack card or standalone DIN-rail PLC module.

Terminal-board matching: Verify the installed board against GE’s approved pairing list. For hazardous-location applications, the exact certified combination must be maintained.

Power: Provide 28.0 VDC nominal, with the documented 27.4–28.6 VDC supply range. The maximum current specified for the relevant power input is 0.17 A DC.

Mechanical fit: Seat the I/O pack squarely against the terminal board. Tighten the retaining hardware evenly; do not use the DC-37 connector as a mechanical alignment lever.

Cooling: Maintain the Mark VIe cabinet’s engineered airflow around the pack and terminal board. Do not impose an arbitrary 50 mm clearance where the cabinet design defines another spacing.

Ethernet: Preserve ENET1/ENET2 network assignments, particularly in redundant or TMR systems. A swapped cable can produce a network fault that resembles a failed I/O pack.

Grounding and shielding: Maintain the original Mark VIe grounding and shield arrangement. Do not substitute field-signal returns for protective-earth conductors.

Hazardous-area installation: Verify enclosure, barrier, cable, terminal-board, and temperature requirements against the certified Mark VIe installation. The I/O pack’s hazardous-location approval is not transferable to an arbitrary cabinet arrangement.

Buyer’s FAQ — Logistics & Compliance Focus

Q: What HS Tariff Code should I use for 336A4940CSP1?
A: A classification under HS 8538.90 is a reasonable candidate for an I/O module used with electrical control equipment. The final national tariff code must be validated against the destination tariff schedule and the actual customs description. Identify it as a GE Mark VIe discrete-input I/O pack, not simply as an electronic circuit board.

Q: What Country of Origin should appear on the commercial invoice?
A: Use the actual manufacturing origin supported by the physical nameplate or GE traceability documentation. Do not use the seller’s warehouse location as COO. For controlled procurement, retain the nameplate image, serial/lot information, COO statement, commercial invoice, and packing list together.

Q: Should I insure an international shipment of one PDIA pack?
A: Yes for a production-critical Mark VIe system. The unit is physically small, with secondary listings reporting roughly 0.5 kg, but the operational cost of losing a 24-point discrete-input interface can be much higher than freight value. Use ESD protection, rigid cushioning, connector protection, tracking, and cargo insurance based on the documented replacement value.

Q: Does the include the latest firmware pre-loaded?
A: Do not assume that. The PDIA contains a processor board and application-specific acquisition hardware, so software compatibility belongs to the Mark VIe control-system environment. Verify the I/O application, hardware revision, and ControlST/Turbine Control configuration before commissioning rather than relying on a generic “latest firmware” statement.

Q: Can I use any STCI or TBCI board with the PDIA?
A: No. GE identifies specific compatible terminal boards, and the hazardous-location certificate narrows the approved combinations further. The IS200STCIH1A, IS200STCIH2A, IS200STCIH8A, IS200TBCIH2C, and IS200TBCIH4C combinations are documented for the .
