To prevent signal degradation and cross-channel interference, each of the 16 channels features independent electrical isolation. This architecture is engineered to maintain high measurement accuracy by minimizing ground loops and common-mode noise, which is critical when processing low-voltage signals such as thermocouples or RTDs alongside higher-level current or voltage inputs.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 16 channels be configured for different signal types simultaneously?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the S9981DE-01 supports multi-signal input types across its 16 channels. Specific channel mapping and sensor-type configuration are defined within the STARDOM engineering software environment.\u003c\/p\u003e\n\u003cp\u003eQ: Does the unit provide excitation power for RTD sensors?\u003c\/p\u003e\n\u003cp\u003eA: The hardware includes integrated excitation circuits required for resistive temperature detector (RTD) measurements.
