Product Details:

The GE IS220PDIIH1B, part number 336A5026ADP1, is a high-reliability Discrete Input I/O Pack Module (PDII) designed for GE Speedtronic Mark VIe distributed turbine control systems. This industrial control spare part collects field discrete contact signals and transmits digital status data to the main controller. As a reliable Turbine Control Module, it works with SDII or TBDT series terminal boards, gathering contact feedback signals from limit switches, breaker auxiliary contacts, pressure switches and safety interlock devices. Each channel adopts optical isolation to block field noise and transient voltage interference, ensuring stable signal acquisition for gas turbines, steam turbines and compressors.

The GE IS220PDIIH1B Discrete Input I/O Pack Module is equipped with dual 10/100Mbps IONet Ethernet ports for redundant network communication, supporting hot swap maintenance without system shutdown. Front panel LED indicators show module running status, network link and channel fault alarms. It adopts conformal coated PCB to resist dust, moisture and vibration in harsh power plant cabinet environments. Built-in channel self-diagnostic functions can detect open circuit, short circuit and signal abnormality faults. The module supports simplex, dual and TMR redundant system architectures and I/O rack mounting inside Mark VIe control cabinet. It is widely used in power generation and oil & gas industries for turbine control system maintenance, spare part replacement and system retrofit.
