Description

Hardware & Electrical Specifications

• Model：IS200TPROH1C
• Part Number：IS200TPROH1C
• Module Type：TPRO TMR‑capable Protection Terminal Board
• Mounting：Cabinet panel mounting inside turbine control cabinet
• Power supply：+24 V DC auxiliary power supplied by PPRO I/O packs
• Input channels：Multi‑channel protection discrete input channels, support dry‑contact and 24‑125 VDC wet‑contact signal
• Isolation：Built‑in isolation transformers, high galvanic isolation rating
• Response time：Typical ≤1 ms for safety trip‑signal response
• Interface：Two barrier‑type removable screw terminal blocks for field wiring; multiple 37‑pin IDC ribbon‑cable connectors for PPRO I/O pack interconnection
• PCB treatment：Conformal coated for dust‑moisture‑corrosion resistance
• On‑board protection：ESD protection, surge suppression, transient absorption circuit for safety‑signal loops
• Compatibility note：Cannot run standalone; must match PPRO protection I/O pack; TMR system requires three‑set hardware consistency verification; full protection‑loop simulation test mandatory after replacement.

Main Functions

1. Removable barrier screw‑terminal field termination for turbine critical safety protection signals: backup overspeed trip, vibration trip, low‑oil‑pressure trip, ESD emergency‑shutdown contact signals.
2. Built‑in isolation transformers provide galvanic isolation between plant field wiring and control logic side, suppress ground‑loop noise and industrial surge interference.
3. Condition protection discrete signals and transmit to three PPRO I/O packs via multi‑ribbon‑cable interface for turbine protection voting‑logic processing.
4. Surge and transient suppression for long‑distance field wiring under high‑EMI turbine‑hall environment.
5. On‑board channel self‑diagnosis: detect field‑loop open‑circuit / abnormal fault, report fault status to turbine main controller.
6. On‑board self‑diagnosis: detect terminal‑board auxiliary power loss and ribbon‑cable link failure.
7. LED status indication:
   • Green LED：Terminal‑board auxiliary power normal
   • Yellow LED：Ribbon‑cable link communication active
   • Red LED：Field‑protection‑channel fault / link communication loss alarm

Installation & Wiring Requirements

1. Cut off rack power supply before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling PCB board.
2. Secure panel mounting firmly; ensure all 37‑pin IDC ribbon‑cable connectors fully locked without loose contact.
3. Field safety‑protection‑signal wiring strictly follow GE Speedtronic Mark VI wiring manual; safety‑related signal cables adopt shielded twisted‑pair, strictly separated from high‑power cables; connect shielding to dedicated ground terminal.
4. Complete protective grounding according to GE Speedtronic system specification.
5. After replacement: verify ribbon‑cable link status, simulate each protection trip‑signal input, validate turbine trip‑logic response before commissioning.
6. Replacement note: For TMR triple‑redundant safety‑loop application, three‑set TPRO channel consistency must be verified; full safety‑protection‑loop simulation test is mandatory after swap.
