Product Introduction

The GE IS220PDIOH1A combines discrete input and relay-output functions in a single Mark VIe distributed I/O pack. It provides the interface between one or two I/O Ethernet networks and a compatible discrete terminal board, with the pack accepting up to 24 contact inputs and controlling up to 12 relay outputs. That combined architecture reduces the number of separate I/O-pack functions required at the field interface (but it does not eliminate the need to verify the correct terminal-board assembly).

Installation identity matters here. GE’s documentation specifically associates the IS220PDIOH1A with IS200TDBSH2A and IS200TDBTH2A terminal relay boards for the documented configuration, while the terminal board determines important field-voltage characteristics. The module uses a DC-62 field interface, dual RJ-45 Ethernet ports, and a three-pin power connection; those interfaces should be checked before any replacement is scheduled.

Core Technical Specifications

Electrical architecture note

PDIO is functionally similar to combining separate discrete-input and relay-output I/O-pack functions into one assembly. GE system documentation identifies 24 discrete inputs plus 12 type-C mechanical relay channels for the PDIOH1A configuration.

The terminal board is not a passive accessory. Its design determines the applicable field voltage and contact-wetting characteristics. For the H1A configuration, GE hazardous-location documentation identifies TDBSH2A and TDBTH2A as the approved terminal-board partners and specifies a 28 VDC nominal, 0.81 A maximum pack supply.

Revision control

Do not assume every IS220PDIOH1A suffix or revision is physically interchangeable. Public records identify units such as IS220PDIOH1AD, IS220PDIOH1AE, and IS220PDIOH1AG as later assembly revisions. The full catalog number, separate assembly-revision marking, terminal board, and ControlST/system revision should be checked together.

Global Compliance & Industry Certifications

The has an important distinction between general industrial use and hazardous-location system certification.

GE hazardous-location documentation specifically lists the with IS200TDBSH2A or IS200TDBTH2A as an approved Mark VIe I/O-pack system combination and identifies an Ex nL IIC T4 protection classification for the PDIOH1A configuration. This is a system configuration requirement, not a basis for treating an arbitrary bare I/O pack as universally hazardous-area certified.

For compliance-controlled procurement:

• CE: Verify against the applicable Mark VIe equipment/system declaration.
• UL/cUL: Confirm the exact GE assembly and installation configuration.
• ATEX: The documented H1A hazardous-location configuration is specifically tied to the approved terminal-board and distributor/power arrangement.
• IECEx: Do not assume an IECEx approval merely from the ATEX designation; verify the exact certificate applicable to the project.
• Marine / DNV-type approvals: Not established for the standalone module unless supported by project-specific certification.
• Country of Origin: Obtain from actual manufacturing/traceability documentation.
• HS classification: Confirm with the importing country’s customs broker; a generic electronic-board heading should not be treated as universally binding.

Verify specific lot certifications with OEM.

For regulated installations, retain the complete part number, assembly revision, serial/traceability information, terminal-board identity, and applicable certification documents together.

Long-Term Storage & Asset Preservation Guide

Keep the PDIO pack in an ESD shielding bag until installation. Protect the RJ-45 connectors and DC-62 interface from dust and mechanical impact; bent contacts or contaminated connectors can create faults that resemble network or I/O failures.

Use a dry, temperature-stable warehouse with no condensation. For long-term industrial-spares storage, maintaining relative humidity below approximately 60% RH is a practical target even when the broader equipment specification permits higher non-condensing humidity.

Before issue to the maintenance team, inspect the enclosure, board surfaces, terminal interface, connector retention, and diagnostic indicators. Record the exact revision marking and serial/traceability information.

Do not mix H1A revisions in inventory without a compatibility record. A physically similar replacement can still be the wrong engineering revision.

Physical Installation Prerequisites

Install the only with the approved compatible Mark VIe terminal-board assembly. For the H1A configuration, the documented pairings are IS200TDBSH2A and IS200TDBTH2A. The correct terminal board is central to the field-voltage and relay-output configuration.

Verify the cabinet’s 28 VDC I/O-pack supply before energizing. Do not substitute a generic 24 VDC supply without confirming that the actual Mark VIe architecture permits it; the documented H1A electrical rating is 27.4–28.6 VDC for the specified configuration.

Secure the pack mechanically and fully engage the DC-62 connector. Check both Ethernet ports against the intended IONet architecture and confirm grounding, cable routing, and cabinet environmental conditions before commissioning.

The relay outputs can handle substantially higher current than typical electronic discrete outputs, so field-load wiring deserves particular attention. Suppression for inductive loads should follow the system design and relay-contact requirements.

Do not remove or install the pack under power unless the OEM documentation and plant maintenance procedure explicitly authorize that operation.

Buyer’s FAQ — Logistics & Compliance

Q: What HS tariff code applies to ?
A: The item is an industrial discrete I/O pack, but the final HS classification depends on the importing country’s tariff schedule and customs interpretation. Use the broker-confirmed code for the commercial invoice rather than assuming one universal classification.

Q: How should Country of Origin be established?
A: COO should be supported by manufacturing or traceability documentation for the actual unit or lot. Seller location, warehouse location, and export port do not establish manufacturing origin.

Q: Does the arrive with the latest firmware pre-loaded?
A: Do not assume it. The PDIO pack contains processor and acquisition hardware, while operational configuration is tied to the Mark VIe control-system environment. Verify the installed hardware revision and approved ControlST/system configuration before commissioning.

Q: Is the hot-swappable, and what should be checked before replacement?
A: Do not assume hot replacement. Follow the applicable GE and plant power-isolation procedure. Before installation, verify the complete identity, separate assembly revision, compatible TDBSH2A/TDBTH2A terminal board, IONet topology, 28 VDC supply, connector condition, and incoming functional-test record.
