About the IS420YAICS1B

The IS420YAICS1B is an Analog I/O Pack that was manufactured by GE Energy. This pack is from the Mark VIe Series. 

IS420YAICS1B I/O Pack Intended Functionality

The IS420YAICS1B can:

• interface between up to two Ethernet networks and a terminal analog I/O board
• handle up to ten analog inputs
  • two of which can be configured as ±1 mA or 4-20 mA current input
  • the remaining eight are ±5 V or ±10 V inputs, or 4-20 mA current loop inputs
• send and receive data through dual RJ45 Ethernet connectors

Additional IS420YAICS1B Device Hardware Information

This IS420YAICS1B I/O Pack is made up of two components:

• one common processor board
• one data acquisition board
  • diagnostic fault detection processes are completely handled solely through its data acquisition board

The associated terminal boards adopted in the robustly-supported modular assembly of the YAIC Analog I/O Pack here are the TBAISIC and STAIS2A terminal boards, which are both also considered component members of the greater Mark VIe Turbine Control System Series. While a variety of the units in the Mark VIe Series can be used in dual, TMR, or simplex redundancy applications, the IS420YAICS1B I/O pack can only be used in TMR or simplex applications. 

IS420YAICS1B Device Diagnostic Detail

The IS420YAICS1B I/O pack can perform several self-diagnostic tests, some of which are:

• a power-up self-test that will check the:
  • flash memory
  • RAM memory
  • most of the processor board hardware
  • the Ethernet ports on the pack

This pack can also continuously monitor the internal power supplies to ensure correct operation.
