GE Fanuc IS200EAUXH1AAA TMR Auxiliary Function Module

GE IS200EAUXH1AAA TMR Auxiliary Function Module

The GE IS200EAUXH1AAA, also cataloged as the IS200EAUXH1AAA auxiliary module, serves as the primary EAUX I/O interface board used to execute auxiliary‑function routing across EX2100E excitation platforms. It provides relay grouping, jumper‑based configuration, ground‑detector interfacing, and control‑slot identification through its onboard ID device.

Hardware Specifications

Triple Modular Redundancy (TMR) 2oo3 Architecture

Within EX2100E excitation systems, the EAUX module aligns with TMR control behavior by providing deterministic auxiliary‑signal routing to M1/M2/M3 controllers. Although the board itself contains no programmable logic, its relay grouping and jumper configuration maintain predictable propagation paths required for 2oo3 voting. Galvanic isolation between relay sets and auxiliary I/O channels supports stable operation under redundant‑rack switching. Firmware flash compatibility resides at the controller level; EAUX hardware characteristics remain fixed across all revision grades.

Frequently Asked Questions

Q: Can the IS200EAUXH1AAA be replaced while the excitation rack is energized? A: No. The module must be inserted or removed only when the associated EX2100E rack segment is de‑energized to avoid transient loading on relay coils and auxiliary I/O channels.

Q: Are there restrictions on configuring jumpers J1–J8? A: Yes. Jumper settings must follow EX2100E documentation to ensure correct auxiliary‑signal routing. Incorrect jumper placement may alter relay‑group behavior or disable specific EAUX functions.

Q: How does the EAUX module behave in TMR redundant configurations? A: The board provides fixed electrical routing; redundancy behavior is governed by controller logic. EAUX hardware does not perform internal voting or switching.

Field Installation Guidelines

• Maintain separation between relay wiring and low‑level auxiliary‑signal lines to reduce noise coupling.
• Ensure conformal‑coated surfaces remain free of abrasion during installation.
• Verify correct alignment of mounting holes and backplane slot guides before seating the module.
• Bond shielded cables at a single termination point to avoid ground‑loop formation.
• Inspect jumper positions prior to energizing the rack to confirm correct auxiliary‑function mapping.
