Product description
The analog I/O package IS420YAICS1B is part of the Mark VIe series produced by General Electric. The I/O packet can be connected between up to two Ethernet networks and a terminal analog I/O board. The kit can handle up to 10 analog inputs, two of which can be configured with ±1 mA or 4-20 mA current inputs, and the remaining eight with ±5 V or ±10 V inputs, or 4-20 mA current loop inputs. The packet can send and receive data via dual RJ45 Ethernet connectors.

While the various units in the Mark VIe series can be used for dual, TMR, or simplex redundancy applications, the IS420YAICS1B I/O package can only be used for TMR or simplex applications, and note that when using this package in TMR redundancy applications, three I/O packages will be used. In a simplex redundant application, only one I/O packet is used. Another important note is that all I/O packages in a TMR set must be in the same hardware form. There is another version of the YAIC I/O package, labeled IS420YAICS1A package, and please note that the package versions cannot be mixed on the same T-terminal board.

The IS420YAICS1B I/O package can perform a number of self-diagnostic tests, some of which are power-on self-tests that will check flash and RAM memory, most processor board hardware, and Ethernet ports on the package. The battery pack also continuously monitors the internal power supply to ensure proper operation.
