Hardware Tips and Specifications

Analogue I/O Pack IS420YAICS1B is part of the Mark VIe series manufactured by General Electric.

This I/O pack allows connection between up to two Ethernet and one terminated analogue I/O board.

The kit can handle up to 10 analogue inputs, two of which can be configured as ±1 mA or 4-20 mA current inputs, and the remaining eight as ±5 V or ±10 V inputs, or 4-20 mA current loop inputs.

The kit can send and receive data over dual RJ45 Ethernet connectors.

For convenience, this IS420YAICS1B I/O package consists of two components; a general processor board and a data acquisition board, as described in the IS420YAICS1B instruction manual that accompanies our manual tab above.

The diagnostic fault detection process for this IS420YAICS1B product is handled entirely through its data acquisition board.

The relevant terminal boards employed in the ruggedly supported modular components of the YAIC analogue I/O kit are the TBAISIC and STAIS2A terminal boards, which are also considered components of the larger Mark VIe turbine control system family.

This IS420YAICS1B device is not actually an original development for its specific Mark VIe Turbine Control System family of features;.

This must be regarded as an IS420YAICS1 parent analogue I/O package, and notably it does not take advantage of the uniquely important Class B functional product revisions of this IS420YAICS1B product.

Whilst various units in the Mark VIe range can be used in dual, TMR or simplex redundancy applications, the IS420YAICS1B I/O package can only be used in TMR or simplex applications.

Note, however, that when using this package in a TMR redundancy application, three I/O packages will be used, whereas only one I/O package will be used in a simplex redundancy application.

Another important caveat is that all I/O packs in the TMR set must be in the same hardware form.
