GE IS200SPROH1ADD Backup Protection Terminal Board

GE IS200SPROH1ADD Backup Protection Terminal Board

The GE IS200SPROH1ADD, also cataloged as the IS200SPROH1A backup protection terminal board, serves as the primary terminal interface used to execute conditioned speed‑signal routing and PT voltage input handling across Mark VIe excitation platforms. Integrated with a PPRO I/O pack, the board provides direct electrical execution of backup‑trip communication and voltage‑monitoring paths.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

As a GE Mark VIe protection‑system component, the SPROH1A/ADD board aligns with deterministic I/O‑pack timing and excitation‑system communication:

• Profinet deterministic networks — stable cycle timing when upstream controllers enforce scheduled exchanges.
• EtherNet/IP deterministic behavior — predictable negotiation windows for CIP‑based traffic.
• I/O density scaling — consistent propagation delay across expanded protection‑system node counts.
• Firmware flash compatibility — PPRO pack firmware governs signal conditioning; the terminal board remains passive.

Frequently Asked Questions (FAQ)

Q: Can the IS200SPROH1ADD be hot‑swapped? A: Terminal boards may be replaced on an energized panel, but PT and speed‑signal wiring must be isolated to avoid transient protection‑system indications.

Q: What wiring gauge is recommended for PT and speed signals? A: Typical installations use #18 AWG conductors for stable low‑level signal routing.

Q: Are SPROH1A and SPROH2A electrically different? A: No. They differ only in terminal‑block style: barrier block (H1A) versus Euro‑block (H2A).

Field Installation Guidelines

• Mount the board on a DIN‑rail sheet‑metal carrier or bolt directly into a panel; ensure rigid retention.
• Maintain separation between PT wiring and high‑current conductors to reduce induced noise.
• Verify full seating of the DC‑37 connector to ensure stable communication with the backup trip relay terminal board.
• Keep terminal blocks accessible for maintenance; label wiring for simplified troubleshooting.
• Avoid flexing the PCB during installation; remove pluggable terminal blocks only when replacing the board.
• Ensure proper grounding of shielded cables to minimize noise on speed‑signal inputs.
