1. Product Overview
IS200TRPAH2AHE TRPA is an external analog front-end conditioning terminal board for GE Mark VIe turbine control systems, mounted on cabinet DIN rail outside the VME rack. It acts as an isolation buffer between field process sensors and high-precision internal VME I/O and servo cards such as WSVO IS210WSVOH1AE.
Front screw terminal blocks directly connect field temperature, pressure, valve position sensors. Built-in dedicated cold junction compensation for thermocouple inputs and constant current excitation for RTD probes eliminate ambient temperature drift and long cable voltage drop errors.
Every analog channel features independent 2000VAC galvanic isolation, MOV surge suppression and multi-stage RC low-pass filters to suppress severe electromagnetic interference from turbine excitation systems, high voltage switchgear and large drive motors in power plant control cabinets.
Rear dedicated flat cable connectors transfer conditioned, noise-free analog signals back to VME backplane processing boards. On-board fault monitoring logic continuously identifies loop failures and uploads millisecond fault timestamps to ToolboxST configuration software and turbine HMI monitoring screens.
Conformal coated PCB and full metal shielding enclosure provide robust environmental resistance for combined-cycle gas turbine, steam turbine and petrochemical cogeneration unit main control cabinets. GE ceased original production; only surplus new stock and refurbished replacement spares are available on the aftermarket.

3. Hardware Composition
1. Front screw terminal blocks for field sensor cable termination
2. Multi-channel signal conditioning PCB: isolation amplifiers, compensation, filter & signal scaling circuits
3. Rear dedicated flat cable connectors for communication with VME rack I/O / WSVO servo cards
4. Full metal shielding housing to block external electromagnetic interference

4. TRPA vs TNSV vs WSVO Functional Distinction
• IS200TRPAH2AHE (TRPA): External DIN rail analog conditioning terminal board, only signal isolation/filter/compensation, no servo drive output
• IS230TNSVH3A (TNSV): Higher-density multi-channel analog terminal board, different terminal layout and flat cable pinout from TRPA
• IS210WSVOH1AE (WSVO): Internal VME servo control card, provides 4–20mA servo valve drive and hardware PID closed-loop position control using LVDT signals fed from TRPA/TNSV boards
• Typical signal chain: Field sensor → TRPA/TNSV isolation board → WSVO servo card closed-loop regulation
5. Main Turbine Application Scenarios
• Combined-cycle gas turbine Mark VIe rack: Combustor RTD, exhaust thermocouple, fuel valve LVDT signal pre-processing & isolation
• Steam turbine control cabinet: Main steam pressure 4–20mA transmitter and valve opening feedback signal conditioning
• Petrochemical cogeneration turbine unit: Multi-point bearing temperature thermocouple centralized signal isolation
• TMR triple redundant Mark VIe systems, universal analog front-end isolation for all process measurement points
