Product Overview

IS220PDIOH1A is mixed discrete input‑output module for GE Mark VIe turbine‑control platform. It interfaces turbine‑plant field‑discrete signals, interlock‑status feedback and drive external relay‑based actuation circuits for gas‑turbine, steam‑turbine and combined‑cycle power‑plant control systems. Critical safety‑related I/O hardware for power‑generation equipment. Surplus and refurbished tested spare module for power‑plant control‑system overhaul and spare‑part stocking.

Application Notes

‑ Strict ESD anti‑static handling rules must be followed during replacement. ‑ Verify field‑loop voltage and polarity before power‑on. ‑ Typical deployment: Mark VIe turbine‑control discrete‑I/O‑module spare‑part stocking.
