GE IS200TPROH1C Emergency Protection Terminal Board

GE IS200TPROH1C Emergency Protection Terminal Board

The GE IS200TPROH1C, also cataloged as the IS200TPROH1C terminal board, operates as a dedicated hardware component for conditioned PT voltage inputs and magnetic‑pickup speed signal routing within Mark VIe emergency protection networks. Three PPRO I/O packs mount directly to the board, with DC‑37 connectors providing trip‑relay cabling paths.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

Although TPRO is a passive terminal board, its interaction with PPRO I/O packs aligns with Mark VIe deterministic network timing. Speed signals, PT voltages, and 4‑20 mA inputs are sampled at fixed intervals defined by the PPRO firmware. Electronic ID devices on TPRO and backup trip boards are interrogated during startup; mismatches trigger hardware‑incompatibility faults. I/O density scaling remains stable across simplex and TMR pack configurations, with ORed 28 V supplies ensuring continuous P24 availability even if one pack is offline.

Frequently Asked Questions

Q: Can IS200TPROH1C be hot‑swapped while the cabinet is energized? A: No. Removal or insertion must occur only when the associated PPRO packs and cabinet segment are de‑energized to avoid undefined trip‑relay states.

Q: How does the board maintain P24 availability in TMR systems? A: The 28 V supplies from R, S, and T packs are ORed, allowing P24 to remain available even if one pack is turned off.

Q: What happens if 240 V ac and dc wiring are cross‑connected? A: The combined peak voltage exceeds MOV ratings, causing MOV failure. Proper segregation of ac and dc wiring is mandatory.

Field Installation Guidelines

• Mount the board and insulator on a DIN‑rail carrier or sheet‑metal assembly.
• Use #18 AWG wiring for PT inputs and magnetic‑pickup speed signals.
• Ensure barrier terminal blocks are fully seated; remove blocks only when replacing the board.
• Maintain strict segregation between 240 V ac and 125 V dc wiring to prevent MOV overstress.
• Verify jumper positions (JPX/JPY/JPZ) according to input type:
  • Thermocouple: positions 1, 4, 7, 10
  • 4‑20 mA: positions 3, 6, 9, 12
• Confirm DC‑37 connectors are latched securely to trip‑relay terminal boards.
• After energizing, validate electronic ID scans and PPRO diagnostic states.
