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. The Mark VI Series is able to attract some more niche demand on its greater automated industrial marketplace as it is one of the final-developed GE Mark product series to introduce the patented Speedtronic control system technology across a range of its different offerings, with the Speedtronic technology first being introduced with the advent of the Mark I in the later 1960s.
Hardware Tips and Specifications
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 The electronics technology for the Mark VIe I/O packs introduced in 2004 is obsolete.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.
The IS220PDIOH1B has a minimum voltage rating of 27.4 VDC, while the nominal rating is 28.0 VDC. The unit and its associated terminal boards have specific field wiring connection instructions that must be followed, including wire size and screw torque. There are twenty-four field terminals when using the TDBS or TDBT boards on the IS220PDIOH1B. All of the positive terminals are labeled as contact-wetting inputs. Each of the terminals on the model differs between negative and positive terminals. For more information on the terminals, refer to the last page of the data sheet above. The IS220PDIOH1B unit is a Discrete I/O Pack part of the General Electric Speedtronic Mark VI/VIe/VIeS gas turbine control modules with accessory combinations approved for use in hazardous locations. When the IS220PDIOH1B model is being operated in the chosen system, it is used with several terminal boards; some of the terminal boards used are labeled as follows:
- ISx0yTDBSH2A
- ISx0yTDBSH8A
- ISx0yTDBTH2A
- ISx0yTDBTH8A
