Description
GE IS230TNDSH2A – Discrete Simplex DIN Rail Terminal Board
GE IS230TNDSH2A is a discrete I/O terminal board designed for GE’s Mark VIe and Mark VIeS turbine control systems, providing simplex field wiring interface for PDIO (Pack Discrete Input/Output) modules. This DIN rail-mounted board supports 24 high-density discrete inputs and 12 outputs with screw-clamp terminals, enabling direct connection of field devices like pressure switches, valve position indicators, and relay contacts in gas turbine applications. It addresses wiring consolidation challenges by offering point-to-point isolation, transient suppression, and compatibility with TMR packs through redundant connector pairs, ensuring reliable signal transmission in vibration-intensive environments. The GE IS230TNDSH2A facilitates hot-pluggable I/O pack replacement without process interruption.
