The GE IS200WNPSH1A (and its variant IS200WNPSH1AAA) is a power supply daughterboard engineered by General Electric for the Mark VIe Speedtronic™ turbine control system. The GE IS200WNPSH1A converts +28 V DC input from the PVIB (Vibration Monitor Module) into a regulated –28 V DC output with ±5% tolerance, powering vibration probes, low‑level signal conditioning circuits, and current‑limited outputs. The IS200WNPSH1AAA provides 14 individually buffered outputs and is mounted directly on the Terminal Voltage Board Assembly (TVBA), supporting triple‑modular redundancy (TMR) configurations. With robust diagnostic features, including open circuit detection and cable ID verification, the GE IS200WNPSH1A ensures reliable power delivery for critical turbine monitoring and protection circuits.
Vibration monitoring systems – powers proximity probes, accelerometers, and velocity sensors in Mark VIe turbine control
Terminal Voltage Board Assembly (TVBA) – provides ±28 V DC to TVBA terminal boards for vibration I/O
Analog signal conditioning – supplies stable power to low‑level analog input modules and transducer loops
Industrial power generation – gas and steam turbine control cabinets, combined‑cycle plants
Precision measurement circuits – powers 4–20 mA loops, RTD inputs, and valve position sensors
Redundant (TMR) control systems – supports triple‑modular redundant configurations with three independent WNPS boards
+28 V to –28 V DC conversion – provides bipolar power with ±5% voltage regulation for analog and precision circuitry
14 individually buffered outputs – each rated at 12 mA, ensuring isolated and stable power distribution to downstream components
TMR‑ready redundant architecture – three independent WNPS daughterboards share a common –28 V bus, enabling seamless failover
Hot‑swap capable – supports online replacement in redundant configurations without system shutdown
Diagnostic intelligence – open circuit detection for vibration inputs; ID devices in cable connectors verify hardware compatibility
Conformal coating – protects against moisture, dust, and corrosive atmospheres for harsh industrial environments
Low ripple output – ≤1% ripple ensures stable, noise‑free power for sensitive analog measurements
Modular design – removable daughterboard simplifies maintenance and replacement without compromising TVBA integrity
VME backplane integration – operates as a dedicated power source for analog I/O and signal conditioning circuits
Converts +28 V DC to –28 V DC – generates regulated bipolar power from the PVIB module for analog and sensor circuits
Distributes isolated power – provides 14 buffered outputs, each delivering 12 mA to vibration probes, transducers, and I/O boards
Supports redundant operation – when configured with three WNPS boards (R, S, T channels), current sharing enables failover without service interruption
Monitors cable and hardware integrity – interrogates ID devices in cable connectors to detect mismatches and trigger alarms
Protects against faults – overcurrent and short‑circuit protection prevent downstream damage to sensitive components
Q1: What is the difference between IS200WNPSH1A and IS200WNPSH1AAA?
A1: The IS200WNPSH1A and IS200WNPSH1AAA are functionally identical – the WNPSH1AAA variant is a later hardware revision. Both provide +28 V to –28 V conversion with 14 buffered outputs.
Q2: Is the IS200WNPSH1A hot‑swappable?
A2: The IS200WNPSH1A supports hot‑swap in redundant (TMR) configurations. However, in simplex setups, power down the VME chassis before removal to prevent damage.
Q3: What is the maximum current output of the IS200WNPSH1AAA?
A3: The IS200WNPSH1AAA delivers up to 400 mA continuous across all channels, with normal load distribution totaling ~540 mA.
Q4: Which terminal boards are compatible with the IS200WNPSH1A?
A4: The IS200WNPSH1A is designed for the TVBAH#A and TVBAS#A terminal boards, powering vibration probe circuits and analog I/O modules.
Q5: Does the IS200WNPSH1AAA have diagnostic capabilities?
A5: Yes. The IS200WNPSH1AAA features open circuit detection and ID device interrogation to verify cable compatibility, triggering alarms on mismatches.
