About the IS220PVIBH1A
This IS220PVIBH1A Vibration Monitor I/O Pack printed circuit board product offering from General Electric was originally designed and manufactured specifically for placement in the Mark VI Turbine Control System Series, as should have been revealed above. The Mark VI Series that this IS220PVIBH1A Vibration Monitor I/O Pack product in specific can be attributed to as a component member exists as quite the significant functional upgrade from the previously-released Mark V Turbine Control System Series of a similar full extended series title, as the Mark V Series' established gas and steam turbine applications added the alternative energy-focused wind turbine possible functional product application with the addition of the Mark VI Series. This IS220PVIBH1A Vibration Monitor I/O Pack printed circuit board I/O Pack product offering's Mark VI Series is also generally held in high regard as it is one of the final-developed GE Mark product series to make use of the patented Speedtronic control system technology across a number of products.
Hardware Tips and Specifications
The IS220PVIBH1A model was designed as a Vibration Monitor Pack. The main function of the PVIB pack is to provide an electrical interfacing function between up to two I/O Ethernet networks and a vibration terminal board. The main components of this pack are the main processor board which is used with a majority of the MK VIe distributed I/O packs as well as a daughterboard and an acquisition board. This IS220PVIBH1A Vibration Monitor I/O Pack device is actually not the orginally-developed device of its specific General Electric Mark VI Turbine Control System Series functionality. That device would have to be deemed the IS220PVIBH1 Parent Vibration Monitor I/O Pack not making use of this IS220PVIBH1A Vibration Monitor I/O Pack product's singular A-rated functional product revision. There are thirteen channels on this pack which are used for collecting and reading proximity and vibration information through several sensor types which are as follows:
- Velomitor
- Seismic
- Proximitors
- Accelerometers
The sensor types are used with different channels, for example, the accelerometers are only used with channels one, two, and three. Please note that channels nine, ten, eleven, and twelve can only be used in supporting proximitors while the thirteenth channel can input a proximity-type or Keyphasor signal type. Note that the thirteen differential inputs on the IS220PVIBH1A pack have a DAC (digital analog converter) which is used for bias adjustment which can void the DC content of the signal which will better center the A/D (analog-to-digital) input range. The PVIB I/O pack has a processor application code that is used to potentially contain all of the logic codes necessary to allow the pack to operate from singular or dual Ethernet inputs. The network paths necessary to properly operate the IS220PVIBH1A pack are active at all times when being operated from two Ethernet inputs. If for any reason either network fails it will not result in any type of disturbance to the operation of the I/O pack but the failure will be indicated through the operating network connection.
