2. Functional Description
IS210DRTDH1AA is a UCSB safety controller module developed by General Electric, designed exclusively for Mark VIe and Mark VIeS industrial turbine control systems (gas turbines, steam turbines). It undertakes core administration and safety control of turbine equipment, and forms Safety Instrumented System (SIS) safety loops with matched safety I/O modules.
This self-contained standalone computing unit has an integrated power supply, no backplane dependency, no on-board battery, and no jumper configuration required. It runs the QNX Neutrino real-time multi-tasking operating system, and communicates with distributed I/O packs via dedicated IONet private industrial Ethernet.
Core Safety Capability
- Complies with IEC 61508 functional safety standards, supports SIL 2 and SIL 3 safety loop applications.
- Certified for hazardous industrial environments with special installation specifications.
- Data synchronization between controllers is auto-executed in Dual / TMR redundant architectures.
