GE Vernova IS420PVIBH1B Mark VIe Vibration Monitor I/O Pack

Mark VIe Vibration Monitoring

GE Vernova IS420PVIBH1B Mark VIe Vibration Monitor I/O Pack

A vibration-monitoring I/O pack documented for Mark VIe hardware with model-specific terminal-board and negative-supply accessories.

Product Overview

GE Vernova IS420PVIBH1B is a Mark VIe vibration monitor I/O pack. This exact order number is distinct from the earlier IS220PVIBH1A hardware.

The approved hardware combination uses an IS200TVBAH2A terminal board and three negative power-supply daughterboards selected from the documented IS200WNPSH1A, IS400WNPSH1A or IS40yTVBAH2B families.

The pack accepts vibration and position input ranges, provides buffered outputs and supplies negative probe power. Selection therefore depends on the complete I/O-pack number and the matching terminal-board assembly.

Monitoring and Signal Interfaces

Vibration, position and buffered signal paths

The electrical ratings separate vibration inputs, position inputs, buffered outputs and probe power. These ranges belong to the PVIBH1B/YVIBS1B hardware class and should not be copied to another vibration pack revision.

Vibration inputs span −20 to 15.6 VDC.
Position inputs span −20 to −0.5 VDC.
Probe power is centered at −24 VDC.

Installation and Hardware Pairing

Use the documented Mark VIe accessory set

IS420PVIBH1B is approved with IS200TVBAH2A and three negative power-supply daughterboards from the listed compatible families. The complete accessory combination must be checked before replacement.

Match the exact IS420PVIBH1B pack identity.
Retain the IS200TVBAH2A terminal-board assignment.
Verify all three negative-supply daughterboards.
