GE’s Mark VIe system guide identifies IS220PAOCH1A as the PAOC Analog Output pack, providing up to eight simplex 0–20 mA current-loop outputs. The pack uses dual RJ45 Ethernet connections, a 3-pin power input, and a DC-37 connection to the associated analog-output terminal board.

Product Introduction

Architecture Hook

Mounted directly on the appropriate Mark VIe analog-output terminal board, the IS220PAOCH1A forms the active electronics portion of the PAOC I/O channel. The terminal board handles the field-side termination, while the PAOC pack performs signal processing and provides up to eight 0–20 mA outputs with current feedback. Dual Ethernet ports connect the pack to one or more I/O Ethernet networks.

The terminal-board revision is not a minor purchasing detail. GE documentation states that PAOCH1A is fully compatible with TBAOH1C and the applicable STAO arrangement, while earlier TBAO revisions can physically accept the pack but may not achieve full analog accuracy because of circuit differences. That is a direct receiving-inspection checkpoint, not a catalog footnote (a wrong terminal-board revision can produce a compatibility problem without physically damaging the pack).

Core Technical Specifications

*These detailed values are supported by current independent technical records; the GE system documentation should remain the controlling reference for engineering acceptance. GE’s lifecycle notice states that the original Mark VIe I/O-pack electronics introduced in 2004 became obsolete and that updated electronics were introduced in 2010.

🚨 Global Compliance & Industry Certifications

• CE Mark: Mark VIe system-level CE conformity may apply to the complete certified assembly. Do not assign standalone CE status to the PAOCH1A without matching documentation.
• UL/cUL: Do not record a standalone UL or cUL claim unless the certificate scope explicitly covers the exact PAOCH1A configuration.
• Class I, Division 2: Independent technical records identify the H1A pack as non-incendive Class I, Division 2, Groups A, B, C, D. This classification matters because electrical equipment installed in such areas must not introduce an ignition source under the defined abnormal conditions.
• ATEX/IECEx: Do not assume standalone ATEX or IECEx approval. The hazardous-area certificate must cover the exact equipment configuration and installation conditions.
• Marine / DNV GL: No exact PAOCH1A-specific DNV GL certificate was verified from the sources reviewed. Marine acceptance should be established from the complete Mark VIe system documentation.
• EMC: GE’s Mark VIe documentation defines the PAOC as part of the distributed I/O architecture, so grounding, Ethernet shielding, and cabinet installation remain part of the compliance assessment.

Verify specific lot certifications with OEM.

🚨 Long-Term Storage & Asset Preservation Guide

Keep the PAOCH1A in its original ESD shielding bag. The DC-37 interface and dual Ethernet connectors are the most obvious contact points to protect, while the conformally coated PCB still contains exposed connector interfaces that can oxidize during poor storage.

Maintain warehouse humidity below 60% RH where practical. Avoid condensation cycles and direct exposure to turbine-room contaminants. Long-term storage in a stable indoor environment is preferable to uncontrolled containers, especially where temperature changes are large.

Protect the terminal-board mating connector. Never store the pack resting on the DC-37 connector. Use the original packaging or a rigid separator so the connector shell and pins are not loaded mechanically (connector damage can create several simultaneous analog-output faults).

Preserve the terminal-board compatibility record. Record the installed terminal-board model and revision alongside the PAOCH1A serial number. GE’s documentation specifically limits full analog accuracy to defined terminal-board revisions.

No -specific manufacturer instruction was verified requiring periodic capacitor reforming. Use controlled inspection and functional testing before release to service.

Physical Installation Prerequisites

Install the IS220PAOCH1A directly onto the approved analog-output terminal board using the DC-37 interface and the manufacturer’s mounting arrangement. GE identifies TBAOH1C as the compatible TBAO revision and lists STAOH1A as another compatible terminal-board arrangement.

Do not approve a replacement solely because the pack physically mates with an H1A or H1B TBAO. GE specifically states that may mount on earlier boards but will not achieve full analog accuracy because of circuit differences.

The reported pack envelope is approximately 82.6 × 41.9 × 121 mm, with approximately 0.5 kg unit weight in one current technical listing. Verify the actual assembly before cabinet or shipping documentation is finalized.

No GE-specific universal 50 mm clearance requirement was verified for . Preserve the terminal-board manufacturer’s ventilation and service envelope, leaving practical access for the two Ethernet cables, DC-37 interface, 3-pin power connector, mounting studs, and pack removal.

Grounding and shield termination must follow the complete Mark VIe cabinet design. Keep Ethernet and analog signal cabling separated from high-energy switching conductors where the installation drawing requires it.

Before inserting the pack, inspect the DC-37 connector and the terminal-board receptacle. Never force engagement or tighten mounting hardware while the connector is misaligned.

Buyer’s FAQ — Logistics & Compliance Focus

Q1. What HS tariff code should be used for ?
Do not treat one supplier’s tariff declaration as universally correct. One current supplier record reports HS 85389091, while customs classification ultimately depends on the importing country’s tariff schedule and treatment of a dedicated industrial I/O pack.Use a precise description such as “GE Mark VIe PAOC analog output I/O pack, ”, then have the destination-country broker validate the final HS code.

Q2. What about Country of Origin?
Current supplier records report USA as the origin for , but the commercial invoice should use shipment-specific COO evidence rather than a generic product database entry.Retain the supplier declaration, serial number, invoice, and packing list together.

Q3. Should shipping insurance cover replacement value rather than the 0.5 kg physical weight?
Yes. The is compact, but its economic exposure can be significant when eight control outputs depend on one pack. Record serial number, condition, declared value, actual gross weight, package dimensions, and pre-shipment photographs before carrier handoff.

Q4. Does a New Original include the latest firmware pre-loaded?
Do not assume it does. This is an active Mark VIe I/O pack containing processor and acquisition electronics, and software compatibility depends on the installed control-system environment. GE lifecycle documentation also identifies the original H1A technology as superseded by updated H1B technology. Where a newer replacement is considered, check the required ControlST version and system compatibility before installation.

Q5. What is the most important receiving check?
Verify the complete identity and the mating terminal-board revision. GE specifies TBAOH1C compatibility and warns that earlier TBAO revisions can cause a compatibility problem or reduced analog accuracy. Retain the terminal-board model, serial number, condition photographs, COO evidence, certification records, and functional test results in the controlled asset file.
