Description

The IS210DTCIH1A is a GE component manufactured as part of the Mark VI system. The Mark VI was one of the last Speedtronic gas/steam turbine management systems released by GE.This line began in the 1960s with the release of the Mark I. The Mark VI was the third of the series to offer TMR (triple modular redundant) architecture, which increased the reliability and efficiency of even complex turbine systems.The Mark VI was also available as a Simplex system for smaller, less complex units that would not benefit from a TMR setup. The IS210DTCIH1A is a Simplex Contact Input terminal board with Group Isolation. This is a small, compact terminal board designed for DIN-rail mounting. The board is mounted in a plastic holder with clips that attach to the DIN rails. One edge of the board is populated by a 60-terminal Euro-block type terminal strip that has been permanently mounted. Screws 55 and 56 are to be used for the SCOM ground connection. The edge opposite the terminal strip has a 37-pin female D” shell connector with latching fasteners.This can be used to cable to a VCCC or VCRC board. The IS210DTCIH1A is scaled for 24 V dc with an input excitation range from 18 to 32 V dc.Threshold voltage is 50% of the excitation voltage. Excitation voltage is monitored and will trip a diagnostic alarm if it falls below 50% of the nominal voltage.There is no configurable hardware on this PCB. More information on the installation and operation of this board may be found within user guides like the MKVI Turbine Control System Guide, or in datasheets or manuals.
