Frequently Asked Questions about IS220PAICH1B

• Where specifically was this IS220PAICH1B product manufactured?
  • This IS220PAICH1B module was originally manufactured in General Electric’s Salem, Virginia factory plant location.
• Why is this IS220PAICH1B device’s sole revision considered a functional product revision?
  • This IS220PAICH1B PCB’s singular revision can be considered a functional revision as it alters the basic performance specifications and general functionality of the IS220PAICH1B product without making notable sacrifices for aesthetic or durability qualities.

About the IS220PAICH1B

As detailed in the IS220PAICH1B brief product description inserted above for your convenience, this IS220PAICH1B device was originally designed and produced by General Electric, specifically for placement in the Mark VI Turbine Control System Series. The Mark VI Series that this IS220PAICH1B modular assembly belongs to has to be classified as a now-obsolete legacy product series, given the eventual manufacturing discontinuation that was necessitated by a series-wide functional obsolescence in one of the many years past its initial General Electric rollout. This IS220PAICH1B device’s greater Mark VI Turbine Control System Series, while obsolete generally, is still something of a self-explanatory GE Mark product series, given the fact that it exists with a selection of specific functional applications in the management and control systems of General Electric-compatible gas, steam, and even newly-developed wind turbine automated drive assemblies. This IS220PAICH1B product offering’s greater Mark V Turbine Control System Series is additionally lauded for its possession of the patented Speedtronic control system; as it is one of the last-developed Mark product series from GE featuring that patented technology.

Hardware Tips and Specifications

Produced by General Electric, the IS220PAICH1B model is an analog input/output pack part of the Mark VI series. This model is the second version of the PAIC units and operates on a different minimum voltage compared to that of the previous version of the PAIC pack. The minimum voltage for this specific unit is twenty-two and a half volts of direct current. The nominal power supply used with this model is twenty-four or twenty-eight volts of direct current. While the IS220PAICH1B pack is being used in the Mark VI series, it can be used with some accessories otherwise known as terminal boards; the terminal boards used with this specific analog I/O pack are all IS200 boards and are IS200TBAIH1C, IS200TAIH1A, and IS200TAIH2A. The IS200TBAIH1C model is a barrier-type terminal box and requires a minimum wire size of 22 AWG when being connected and used with the IS220PAICH1B pack.

There are specific alarms that will come about when this model is in use, one of the alarms is labeled as 82-83 which focuses on the output and indicates that the suicide relay within the IS220PAICH1B pack is non-functional. The possible cause of this alarm is often that the suicide relay command in the pack does not match the associated feedback, the hardware has failed, or a relay failure has occurred on the acquisition board. The main solution to this problem is replacing the I/O pack itself. The IS220PAICH1B pack can be used in many different locations including hazardous and non-hazardous locations, the certification for the non-hazardous location in accordance with this model is UL E207685. This IS220PAICH1B device is not surrounded by any extreme wealth of originally-released instructional manual materials; almost certainly a reflection of its attribution to the Mark V Turbine Control System Series that suffered a manufacturer-led production and documentation discontinuation. With this being the case, the IS220PAICH1B functional product number can actually be identified as a decently-strong supplementary source of IS220PAICH1B Board hardware information; coding for specific details in a series of consecutive functional naming chunks. For instance, the IS220PAICH1B functional product number begins with a dual-functional initial naming chunk in its IS220 series tag specially designed to indirectly reveal the IS220PAICH1B product’s normal Mark V Series assembly iteration as well as its domestic original manufacture location. Some of the other important hardware details embedded in the IS220PAICH1B functional product number include this IS220PAICH1B device’s:

• PAIC functional product acronym
• Conformal PCB coating style
• Group one Mark V Series product grouping
• B-rated primary functional revision
