Product function

GE IS220PTCCH1B 12 Combustion Optimized Inputs and conditions multiple combustion-related analog signals—such as flame-scanner currents, pressure-transmitter outputs, and thermocouple voltages—and forwards digitized data over the IONet Ethernet bus to the Mark VIe control CPU. Ensures low-latency, high-accuracy feedback for combustion-control algorithms and safety interlocks..
