Original General Electric / GE IS220PDIOH1B +IS200 Discrete I/O Module

About the IS220PDIOH1B

 

This specific IS220PDIOH1B product offering hails from General Electric's Mark VI Turbine Control System Series. The Mark VI Series that this IS220PDIOH1B product belongs to, as based off of its full extended series name, has specific set applications in the management and control systems of General Electric-accepting wind, steam, and gas turbine automated drive assemblies; a marked improvement upon other previously-developed Mark product series given the fact that earlier Mark Series iterations were limited in their scale to steam and gas turbine applications alone.

These terminal boards extend the PDIO packs functionality, as the previous PDIO pack can only work with two accessory terminal boards. The terminal boards are labeled as Intrinsically Safe Apparatus Relay Contact terminal boards. This unit contains two Ethernet ports, a local processor, and a data acquisition board for use within the GE Mark VI Speedtronic Series. The electronics technology for the Mark VIe I/O packs introduced in 2004 is obsolete. The front panel of the IS220PDIOH1B includes LED indicators for both Ethernet ports for the unit's power and an "attn" LED. Additional LEDs are related to relay connections. Before making any ultimate purchase decision on this IS220PDIOH1B product, it is absolutely crucial to understand that this IS220PDIOH1B device is not the original module developed for its specific intended Mark VI Series functional role; that would have to be the IS220PDIOH1 parent PDIO Pack notably not including this IS220PDIOH1B device's B-rated functional product revision in its special Mark VI Series assembly. The entire surface of this IS220PDIOH1B product's base printed circuit board should be assured at least a basic style of protection through the conformal-style PCB surface coating applied as a thin-layer of daily wear and tear PCB protection to the IS220PDIOH1B. Available for both repair or replacement with warrantied protection guaranteed.

What is the IS220PDIOH1B Module?

The IS220PDIOH1B model is a Discrete Input/Output (I/O) Module or Pack. It is used with ISx0yTDBS2A/TDBSH8A or ISx0yTDBTH2A/TDBTH8A.

What are the differences between standard IS200TDBT/TDBS boards used on the PDIOH1A compared to the ISx0yTDBS_8A/TDBT_8A accessory boards?

There are no extreme differences between the two models. The terminal boards are all used in hazardous applications and are labeled an intrinsically safe apparatus with entity parameters. The hazardous locations in which the two terminal boards will be used are slightly different but have the same functionalities.
