Product Details:

The GE IS220PDIOH1B, part number 336A5026ADP6, is a high-performance Discrete I/O Pack Module developed for GE Speedtronic Mark VIe distributed turbine control systems. This industrial control spare part is used for digital signal acquisition and relay output control. As a reliable Turbine Control Module, it collects discrete status signals from limit switches, pressure switches and equipment contact feedback, and outputs relay commands to control solenoid valves, alarm indicators and auxiliary interlock devices for gas turbines and steam turbines. It can cooperate with TDBS/TDBT series terminal boards to complete the whole discrete signal loop.

The GE IS220PDIOH1B Discrete I/O Pack Module is equipped with dual 100Mbps IONet Ethernet ports for redundant network communication, ensuring stable real-time data exchange with the main controller. It supports simplex, dual and TMR redundant system architectures and allows hot replacement without full system shutdown. Front panel LED indicators display power status, communication link and channel faults in real time. Built-in comprehensive channel diagnostic functions can detect signal loss, open circuit and abnormal circuit status. The module adopts ruggedized housing and conformal coated circuit board to resist vibration, dust and moisture in harsh power plant environments. It is widely used in power generation and oil & gas compressor stations for turbine control system maintenance, spare part replacement and system upgrade.
