Product Description

GE IS200TPIMG1A Protective Interface Terminal Board

Configured for discrete trip‑signal routing in Mark VI turbine protection networks, the GE IS200TPIMG1A (TPIM) provides direct physical/electrical execution. It isolates field‑level protection wiring from controller logic, manages E‑Stop and relay feedback circuits, and supports simplex or TMR protection architectures.

Backplane Communication Velocity and I/O Density Behavior

GE Mark VI protection boards maintain deterministic backplane communication velocity to ensure synchronous trip‑signal propagation across TREG, TRPG, TRLY, and TPIM modules. The IS200TPIMG1A operates as a passive interface; it contains no firmware and therefore introduces zero latency beyond physical relay/contact propagation. In TMR systems, TPIM supports 2‑out‑of‑3 voting logic by providing clean, isolated discrete paths for controller‑level voting algorithms.

Frequently Asked Questions

Q: Can the IS200TPIMG1A be removed while the panel is energized? A: No. Removal under power is not recommended. De‑energize the panel to avoid undefined relay states or transient trip signals.

Q: Does the board introduce latency in TMR voting logic? A: No. TPIM is passive; voting latency is determined by the Mark VI controller firmware.

Q: Is the board compatible with TREG and TRPG? A: Yes. TPIM is designed to operate with TREG (positive trip power), TRPG (negative trip power), and TRLY (trip relay board).

Field Installation Guidelines

  • Mount on DIN rail using GE‑approved hardware.
  • Maintain segregation between 24 V dc trip circuits and higher‑energy wiring.
  • Use shielded cable for E‑Stop and relay feedback lines; terminate shields at a single grounding point.
  • Verify fuse seating and continuity before energizing the panel.
  • Ensure terminal blocks are fully latched; avoid over‑tightening screws.
  • Label all field wiring to support maintenance and fault tracing.
  • Confirm correct ribbon‑cable orientation when connecting to controller modules.
