The EMERSON CE4003S2B6 is a high-performance analog input module tailored for the process industries. It provides 16 channels of 4-20mA input, utilizing 16-bit analog-to-digital converters to ensure that process variables like temperature, pressure, and flow are measured with extreme accuracy. This precision allows for tighter control loops, leading to improved product quality and reduced waste in batch and continuous processes.
One of the standout features of the CE4003S2B6 is its native support for the HART (Highway Addressable Remote Transducer) protocol. This allows the module to extract secondary variables and diagnostic data from "smart" field instruments. By passing this data to the DeltaV system, the CE4003S2B6 enables Asset Management Solutions (AMS) to monitor the health of field devices, facilitating a transition from reactive to predictive maintenance.

To ensure high performance in electrically noisy environments, the CE4003S2B6 features significant channel-to-channel and channel-to-logic isolation. Advanced digital filtering is applied to each channel to reject 50/60 Hz noise and other industrial interference. This ensures that the control logic receives a clean, stable signal even when the field wiring is routed near high-voltage cables or variable frequency drives (VFDs).
The module is designed for continuous 24/7 operation. It features an internal reference voltage source that is used for continuous self-calibration, ensuring that the measurement accuracy does not drift over time. If a channel failure is detected, the module reports the fault immediately to the operator console, while the remaining 15 channels continue to operate normally, minimizing the impact of a single-point failure.
Configuration of the CE4003S2B6 is handled entirely within the DeltaV engineering environment. Parameters such as signal range, alarm limits, and HART polling rates are easily set via the software interface. The module’s hot-swappable design and rugged electronics make it a reliable choice for critical control applications in the global energy and chemical sectors.
