Furthermore, the board implements 64 fully isolated input channels to reduce electrical interaction between field signals, processor interfaces, and power supply common points.\u003c\/p\u003e\n\u003cp\u003eThe isolated channel architecture supports low-level millivolt measurement by controlling common mode voltage effects and reducing signal interference. The module provides 80 dB crosstalk suppression across DC to 60 Hz conditions and increases rejection performance to 120 dB at 50 Hz and 60 Hz operation.\u003c\/p\u003e\n\u003cp\u003eFor Honeywell DCS instrumentation, thermocouple interfaces require accurate cold junction compensation (CJC) and stable analog conversion performance.
