Product Overview

IS400JPDMG1AED is discrete‑I/O controller main‑board for GE Mark VIe PDIO rack subsystem. It processes mass discrete‑input status and relay‑output drive logic for turbine interlocks, emergency trip‑circuits and auxiliary‑equipment control. Redundant IONet Ethernet links ensure high‑availability communication with main Mark VIe controller. It works together with terminal‑boards and relay‑sensing boards to implement fault‑tolerant TMR discrete‑control logic for gas‑turbine and steam‑turbine power‑generation units. Obsolete spare hardware available as refurbished and surplus tested assemblies for legacy power‑plant cabinet overhaul projects.

Application Notes

‑ Strict ESD protection required during card replacement. ‑ Match firmware revision with existing Mark VIe system via ToolboxST. ‑ Verify rack supply voltage stays within 18‑32 VDC range. ‑ Typical deployment: power‑plant Mark VIe PDIO controller‑board spare‑part stocking.
