IS200TRPSH1ACC | 24V High-Current Relay Output ACC

Description

Product Introduction (Anti-Template)

The ‘ACC’ suffix on this high-current relay board represents a component variant within the ‘A’ revision family—one of those GE configurations that makes procurement a bit more interesting. The IS200TRPSH1ACC is a TRPS series board with the higher-current relay contacts and improved arc suppression of the ‘A’ revision, combined with the ‘CC’ variant-specific component selection.

What does ‘ACC’ mean in practice? The ‘CC’ portion typically indicates component substitutions—often different high-current relays, contact materials, or connectors driven by supply chain changes or customer requirements. The board retains all functional characteristics of the standard TRPSH1A (higher current rating, improved arc suppression) but may have slightly different contact resistance, switching characteristics, or long-term reliability depending on the substituted parts. If you’re replacing an existing ‘ACC’ board, match the suffix. If you’re substituting a standard ‘A’ for an ‘ACC’, verify the component differences with GE documentation or your OEM.

Key Technical Specifications

Compatible Replacement Models

✅ Drop-in Replacement: IS200TRPSH1A — The standard ‘A’ revision. Identical pinout, mounting, and software interface. The ‘ACC’ uses different component selections. Most applications won’t see a difference.

✅ Drop-in Replacement: IS200TRPSH1 — The base revision. Direct hardware match. The ‘A’ revision (including ‘ACC’) has improved arc suppression.

⚠️ Software Compatible: IS200TRPGH1A — General-purpose relay board with lower current rating. May not be suitable for higher-current loads. Verify contact ratings.

⚠️ Software Compatible: IS200TPROH1A — Triac output board. Handles AC loads only. Requires software reconfiguration.

⚠️ Software Compatible: IS200TBCI1A — General-purpose I/O board. Requires external high-current relays. Budget 6-8 hours.

❌ Hardware Incompatible: IS200TBQGH1A — Excitation termination board. Different pinout and application.

Frequently Asked Questions (FAQ)

Q: What does the ‘ACC’ suffix mean on this TRPS board?

A: The ‘ACC’ suffix indicates a component variant within the ‘A’ revision family. It’s not a standard upgrade path—typically, ‘ACC’ means GE used different components (relays or connectors) due to supply chain changes or a customer request. The board functions identically from a wiring perspective.

Q: Can I replace an ‘ACC’ board with a standard ‘A’ revision?

A: Usually yes—the boards are pin-for-pin compatible. However, some ‘ACC’ variants have different relay contact ratings or contact materials. If those differences matter to your high-current application, match the suffix.

Q: How do I know if I need the ‘ACC’ variant?

A: Check your original bill of materials or the board’s placement in your system. If the board you’re replacing has an ‘ACC’ suffix, replace it with the same suffix.

Q: Is the TRPSH1ACC hot-swappable?

A: We advise against hot-swapping relay boards—especially high-current relay boards where arcing potential is greater. Power down the cabinet segment before swapping.

Q: What bench testing should I do before installing a TRPSH1ACC?

A: Standard relay protocol with load testing. First, visual inspection. Second, verify continuity. Third, measure contact resistance. Fourth, apply power and verify each relay actuates correctly. Fifth, apply a test load at rated current and verify contact performance.

Q: How do I verify I’m getting a genuine TRPSH1ACC?

A: Check component markings against GE’s documented parts list. Weigh the board; should be about 390 grams. Look for the GE holographic security label.

Q: Where do I find the official wiring diagram for the TRPSH1ACC?

A: GE document GEK-130549 covers the TRPS series. The ‘ACC’ suffix typically does not change the wiring diagram. Always cross-reference against your cabinet’s as-built drawings. Verify every channel before terminating.
