GE IS420YDOAS1B YDOA Discrete Output I/O Pack for Mark VIe Turbine Control System

Product Description

IS420YDOAS1B is the YDOA discrete output I/O pack for GE Mark VIe Speedtronic turbine control system. It communicates with Mark VIe controller via dual Ethernet IONet, provides 12‑channel discrete output driving

signals to external terminal board through DB37 connector, supports relay feedback signal detection. Compatible with ControlST configuration software, S‑type conformal coating for harsh plant cabinet environment.

Widely deployed on gas turbine, steam‑turbine, generator protection, compressor anti‑surge control cabinets in power plant and oil‑gas industry.
