The GE IS200WNPSH1A, commonly marked on the PCB as IS200WNPSH1AAA, is a WNPS power supply daughterboard used with the Mark VIe vibration monitoring architecture. GE documentation identifies it as an accessory used with the IS200TVBAH2A terminal board and Mark VIe PVIB vibration monitor modules. The WNPS converts the corresponding +28 VDC supply to -28 VDC required by vibration probes and associated circuitry. Three removable WNPS daughterboards can be used in the TVBA architecture to provide redundant negative power. If one supply is lost, the offline supply can be serviced without removing terminal-board and sensor power.
