About the IS220PIOAH1A
IS220PIOAH1A Series Information
The IS220PIOAH1A is an ARCNET Interface Module or Arcnet I/O pack used in Mark VIe Excitation Control systems. This IS220PIOAH1A ARCNET Interface Module could also be attributed to the Mark VI Series, and perhaps more commonly, which lends to its placement in the Mark VI Turbine Control System Series on our website here.
This IS220PIOAH1A ARCNET special modular product offering's greater mark VI Series is additionally heralded on its greater automated industrial promotional marketplace due to its status as one of the final-developed GE Mark product series exhibiting the esteemed Speedtronic control system technology first coined with the release of the Mark I Series all the way back in 1969.
IS220PIOAH1A Installation
This singular A-rated functional revision can actually be defined as likely the most common General Electric revision style made available to the greater Mark VI Turbine Control System Series, but also the larger Mark Series product suite in general. IS220PIOAH1A mounts directly to the JPDV rack/terminal and can be easily removed if replacement is needed. Installation Instructions for the IS220PIOAH1A can be found in GEH-6800 Vol II but are summarized below:
- Attach the IS220PIOAH1A to the JPDV terminal
- Secure the PIOA by screwing down the connectors
- Attach all relevant cables including the ethernet connections
- Using this connection on the IS220PIOAH1A, and after applying power, configure the I/O pack as required for the application.
Hardware Tips and Specifications
The IS220PIOAH1A is a Communications Bridge I/O pack. Unlike most I/O packs, this component does not have an associated terminal board. However, the JPDV board is its associated interface PCB. I/O packs are mounted on their associated boards to perform extra processes, like algorithmic computations and the digitization of sensor signals. This allows algorithms to run at faster speeds.
The component also communicates with the controller board within the main processor. The I/O has its own processor board installed within its casing. This processor runs on a QNX OS with a 32-bit RISC CPU 266 MHz. The IS220PIOAH1A is built with dual 100 MB Ethernet ports. The case also has a power port. Power for the component is rated at 28 V dc (typical.)
There is also an onboard ambient temperature sensor that will alarm if excessive temperature is noted. The operating temperature of the component is -30 C to 65 C. It is rated Class 1, Div. 2. The front faceplate has several LED status indicators for power status, attention, Ethernet connection and active status. There is an infrared port located below the LEDs in the front panel. This is a transciever used for low level diagnostics or for the setting of host/function names. More information about this pack, its operation and installation, and its components can be found through publications from the manufacturer like user guides and manuals.
