Description
Product Introduction
GE IS220PVIBH1A is the PVIB (Vibration Monitor) I/O pack in GE’s Mark VIe and Mark VIeS turbine control systems, designed to acquire, condition, and process vibration and position data from rotating machinery such as gas turbines, steam turbines, compressors, and generators.nseautomation+1
This 13-channel pack interfaces with proximitor, accelerometer, velomitor, seismic, and keyphasor sensors, provides −24 V DC probe excitation, and transmits digitized data over redundant 10/100 Mbps Ethernet (IONet) to the primary controllers for real-time protection and predictive maintenance.dcsmodule+1
Frequently Asked Questions
Q: Can I hot-swap the IS220PVIBH1A?
A: Yes, in redundant Mark VIe configurations. The PVIB I/O pack is designed for hot-swap replacement when installed in a dual-redundant I/O rack with intact IONet paths, provided the remaining power and communication paths are active. In Simplex systems, you must de-energize the rack before removal to avoid losing all vibration monitoring.worldofcontrols+1
Q: Is the IS220PVIBH1A obsolete? Are there direct replacements?
A: Yes, the PVIB pack is effectively obsolete in new GE production. Direct replacements are other PVIB variants (e.g., IS220PVIBH1B, IS220PVIBH1C) or upgraded vibration I/O packs in the same Mark VIe/VIeS family, but verify mechanical envelope, connector pinout, and BPPB processor compatibility before swapping.worldofcontrols+1
Q: Will I lose my turbine control program when replacing this pack?
A: No. The IS220PVIBH1A is a vibration monitoring I/O module; it does not store control logic or parameters. Turbine control programs reside in the primary controllers (e.g., VCMI, VCMIH). However, always back up the Mark VIe project before any hardware intervention.nseautomation+1
Q: Are these units factory-new or refurbished?
A: Most available stock is New Surplus (original GE packaging, never installed) or tested used units with 12–36 month warranty. Genuine GE factory-new IS220PVIBH1A packs are rare. Request photos of packaging, revision labels (H or later), and serial numbers for audit.ebay+1
Q: What warranty and lead time should I expect?
A: Surplus suppliers typically offer 12–36 months warranty on tested units; New Surplus may have 12–24 months. Lead times: in-stock units ship in 1–3 days, but export paperwork and customs can add 5–8 working days.
