IS200TRPAS1AFD | 24V Special Annunciator Relay AFD Variant

Description

Product Introduction (Anti-Template)

The ‘AFD’ suffix on this specialized annunciator board adds another layer of complexity to an already non-standard variant. The IS200TRPAS1AFD is a TRPAS series board with the ‘S1’ specialized configuration, the ‘A’ revision improvements, and the ‘FD’ variant-specific component selection—a triple-combination that makes this board highly specific to a particular customer or application.

What does ‘S1AFD’ represent? The ‘S1’ indicates a specialized channel configuration, the ‘A’ is the revision with improved LED brightness and contact material, and the ‘FD’ suffix indicates component substitutions—different relays, LEDs, or connectors. The board retains all functional characteristics of the TRPAS1A but may have different relay contact ratings, LED brightness, or long-term reliability. If you’re replacing an existing ‘AFD’ board, match the suffix. If you’re substituting a standard ‘A’ for an ‘AFD’, verify the component differences—or better, consult GE documentation.

Key Technical Specifications

Compatible Replacement Models

✅ Drop-in Replacement: IS200TRPAS1A — The standard ‘A’ revision, S1 variant. Identical pinout, mounting, and software interface. The ‘AFD’ uses different component selections. Most applications won’t see a difference.

✅ Drop-in Replacement: IS200TRPAS1 — The base revision. Direct hardware match. The ‘A’ revision (including ‘AFD’) has improved LED brightness and contact material.

⚠️ Software Compatible: IS200TRPAH1A — Standard annunciator board. Different channel configuration and pinout—may not be a direct match. Verify before substituting.

⚠️ Software Compatible: IS200TREGH1A — Standard relay board without annunciator features. Lacks status LEDs. Requires software reconfiguration. Budget 2-4 hours.

❌ Hardware Incompatible: IS200TPROH1A — Triac output board. Different application and switching characteristics.

Frequently Asked Questions (FAQ)

Q: What does the ‘AFD’ suffix mean on this TRPAS board?

A: The ‘AFD’ suffix indicates a component variant within the ‘A’ revision family, applied to the specialized ‘S1’ configuration. Typically, ‘FD’ means GE used different components (relays, LEDs, or connectors) due to supply chain changes or a customer request. The board functions identically from a wiring perspective.

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

A: Usually yes—the boards are pin-for-pin compatible. However, some ‘AFD’ variants have different LED brightness or relay contact ratings. If those differences matter to your annunciator panel, match the suffix.

Q: What does the ‘S1’ configuration mean?

A: The ‘S1’ indicates a specialized channel configuration—not a standard density variant. These boards were produced for specific customer applications. The pinout and channel mapping may differ from standard TRPA boards.

Q: Is the TRPAS1AFD hot-swappable?

A: We advise against hot-swapping relay boards. Power down the cabinet segment before swapping.

Q: What bench testing should I do before installing a TRPAS1AFD?

A: Specialized board protocol. First, obtain the wiring diagram for this specific variant. Second, visual inspection—compare LED brightness to known standard. Third, verify continuity. Fourth, measure contact resistance. Fifth, apply power and verify each relay actuates and LED lights. Sixth, document the pinout for future reference.

Q: How do I verify I’m getting a genuine TRPAS1AFD?

A: Check component markings against GE’s documented parts list. Weigh the board; should be about 365 grams. Look for the GE holographic security label.

Q: Where do I find the official wiring diagram for the TRPAS1AFD?

A: The ‘S1’ variant and ‘AFD’ suffix may not be covered in standard GEK-130546. You’ll need customer-specific documentation or GE’s variant-specific drawings. Contact GE support with the full part number. If unavailable, reverse-engineer the pinout by tracing continuity.
