GE DS3800NASB1B1C
Product Overview & Core Function
This board provides 8 high-speed analog input channels and 8 analog output channels, both with 16-bit resolution. It is engineered for specialized sensor and actuator interface applications in demanding industrial environments, particularly where standard boards fail due to thermal drift. The 1B1C suffix is a mixed-grade coating configuration: “B” indicates medium-duty conformal coating on the board itself (30–50 microns), while “C” indicates heavy-duty coating on the termination hardware (40–60 microns) for moderate chemical exposure resistance.
