• Module Type：High‑Speed Logic‑Analog Terminal Board (HSLA)
• Mounting：DIN‑rail bracket installation inside turbine control cabinet
• Power supply：+24 V DC / ±15 V DC supplied by system rack backplane
• Speed input：2‑channel magnetic pickup(MPU) / active speed sensor input, max input frequency 20 kHz, jumper‑configurable threshold level
• Analog channel：Multi‑channel high‑speed analog input/output for valve position feedback and control output
• Discrete I/O：Fast digital interlock input & relay‑type output for turbine protection logic
• Communication：HSSL high‑speed serial link interface, connect to corresponding I/O pack via dedicated ribbon cable
• Galvanic isolation：Channel‑to‑channel and field‑to‑logic isolation for anti‑interference in heavy‑industrial environment
• PCB treatment：Conformal coated for dust‑moisture‑corrosion resistance
• On‑board protection：ESD protection, surge suppression, input over‑voltage clamp circuit
• Compatibility note：Cannot run standalone; must match corresponding HSLA I/O core pack; jumper configuration must restore after replacement; full‑loop speed & valve‑control function test required for TMR system。

Main Functions

1. Terminate magnetic pickup pulse signals from turbine shaft for rotating‑speed measurement and overspeed protection logic.
2. Condition high‑speed analog feedback signals from valve LVDT position sensors.
3. Receive fast discrete interlock‑trip signals and output discrete control commands for turbine protection logic.
4. Signal filtering and surge suppression for long‑distance field wiring in high‑EMI power‑plant environment.
5. Transmit conditioned field signals to matched I/O pack via HSSL high‑speed serial link, achieve low‑deterministic‑latency data transmission for governor loop.
6. On‑board channel self‑diagnosis: detect MPU open‑circuit, signal over‑range, loop fault, report fault status to main controller.
7. LED status indication:
   • Green LED：Terminal‑board auxiliary power normal
   • Yellow LED：HSSL link communication active
   • Red LED：Field‑channel fault / link communication loss

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 DIN‑rail mounting bracket firmly; ensure HSSL ribbon‑cable connector fully locked without loose contact.
3. Restore on‑board jumper setting (MPU threshold, signal mode) strictly consistent with original configuration before field wiring.
4. Field‑sensor wiring adopts shielded twisted‑pair; separate speed‑signal cables from high‑power cables to reduce electromagnetic interference; connect shielding to dedicated ground terminal.
5. Complete protective grounding according to GE Speedtronic system specification.
6. After replacement: verify HSSL link status, test turbine‑speed measuring value, validate valve‑position feedback and protection‑signal response before commissioning.
7. Replacement note: Jumper configuration must be reproduced exactly; TMR redundant system requires three‑set channel consistency verification, full‑function test mandatory after swap.
