Description
🔹 Product Description
The GE IS220PVIBH1A is a Vibration Monitor (PVIB) I/O Pack designed for GE Mark VIe turbine control and rotating machinery monitoring applications. It interfaces with the TVBA Vibration Terminal Board and processes vibration, proximity, and related machinery-monitoring signals. The module supports up to 13 input channels, with channel configurations for proximity probes, integrated-output accelerometers, Velomitors, seismic sensors, and Keyphasor/proximity signals depending on the channel. It provides dual RJ45 Ethernet communication, a 3-pin power connection, and a DC-37 interface to the associated terminal board. The PVIB can be deployed in simplex or TMR configurations when used with compatible Mark VIe hardware.
