The DS3800HFPE1B1B is a General Electric Mark IV Speedtronic turbine control board, a thermocouple input module with a detailed suffix code indicating specific factory configurations. The “1B1B” typically denotes: 24-channel differential input (1), firmware revision B1 (B1), and standard environmental protection (B = basic coating). This variant represents an earlier production configuration of the HFPE platform, with firmware optimized for J-type thermocouples and basic humidity resistance.
The DS3800HFPE is a General Electric Mark IV Speedtronic turbine control board, a thermocouple input module from the HFPC/HFPE family with a distinct suffix. The “E” variant typically indicates a different channel configuration, expanded input types, or enhanced diagnostic features compared to the “C” or “B” versions. It processes low-level millivolt signals from temperature sensors with onboard cold-junction compensation and is designed for applications requiring higher channel density or mixed thermocouple types in a single board.
The DS3800HFPC1M1H is a General Electric Mark IV Speedtronic turbine control board, a thermocouple input module with a suffix code indicating: 16-channel differential input (1), firmware revision M1 (M1), and heavy conformal coating (H). The “M1” firmware represents a later revision than “L1,” featuring enhanced cold-junction drift correction and improved EMI filtering for better performance in high-electrical-noise environments such as large generator halls and variable-frequency-drive (VFD) installations.
The DS3800HFPC1L1H is a General Electric Mark IV Speedtronic turbine control board, a thermocouple input module with a comprehensive suffix code indicating specific factory configurations. The “1L1H” typically denotes: 16-channel differential input (1), firmware revision L1 (L1), and enhanced environmental protection (H = heavy conformal coating + extended temperature range). This variant is designed for harsh industrial environments where standard boards may fail due to moisture, dust, or extreme temperatures.
The DS3800HFPC is a General Electric Mark IV Speedtronic turbine control board, a thermocouple input module with a specific configuration variant. Unlike the “B” or “D” suffix versions, the “C” variant typically indicates a different channel count, firmware revision, or front-panel connector pinout tailored for specific turbine frame sizes (e.g., Frame 6B, 7EA, or 9E). It processes low-level millivolt signals from exhaust, bearing, and inlet temperature sensors with onboard cold-junction compensation.
The DS3800HFPB1F1E is a General Electric Mark IV Speedtronic turbine control board, a variant of the thermocouple input module with factory-installed options indicated by the suffix code. The “1F1E” typically denotes specific channel configuration (16-channel differential), firmware revision (F1), and coating type (E = conformal coated for harsh environments). It processes millivolt signals from J/K/T thermocouples with onboard cold-junction compensation.
