Product Details:

The GE IS220PAOCH1A, with part code 363A4940CSP5, is a high-precision Analog Output Pack Module built for GE Speedtronic Mark VIe distributed turbine control systems. This industrial control spare part converts digital control commands from the main controller into stable analog current signals for field actuators. As a reliable Turbine Control Module, it has 8 independent analog output channels supporting 0-20mA signal range, with 16-bit DAC conversion for high precision. It outputs analog signals to regulate fuel valves, steam control valves and positioners, realizing closed-loop flow and pressure control for gas turbines, steam turbines and compressors. It needs to cooperate with TBAO or STAO series terminal boards to form complete analog signal loops.

The GE IS220PAOCH1A Analog Output Pack Module is equipped with dual 10/100Mbps IONet Ethernet ports for redundant network communication, supporting hot swap maintenance without shutting down the whole system. Front panel LED indicators show power, network link and channel fault status. Built-in channel self-diagnostic functions continuously monitor output circuit status, and can detect open circuit, short circuit and signal deviation faults timely. The module adopts conformal coated PCB to resist dust, moisture and vibration in harsh power plant cabinet environments. It supports simplex, dual and TMR redundant system architectures. It is widely used in power generation and oil & gas industries for turbine control system maintenance, spare part replacement and system retrofit.
