General Electric IS420YAICS1B Mark VIe Analog I/O Pack

GE IS420YAICS1B is an Analog I/O Pack designed for integration with Mark VIe and Mark VIeS control systems. The pack interfaces between a terminal analog I/O board and up to two Ethernet networks while supporting ten analog input channels. It incorporates a common processor board and a dedicated data acquisition board, with diagnostic fault detection executed through the acquisition circuitry. The unit supports simplex and TMR architectures and is compatible with TBAIS1C and STAIS2A terminal boards for turbine control applications in gas, steam, and wind power installations.
