Working Principle:
The SE4003S2B2 receives 4-20 mA current signals from field instruments connected to its input channels. Each channel includes precision current-to-voltage conversion circuitry that translates the input current into a proportional voltage signal. This voltage is then digitized by high-resolution analog-to-digital converters. The digital values are processed by the module’s microprocessor, which applies calibration factors and scaling to produce engineering unit values. These values are transmitted to the DeltaV controller via the internal DeltaV communication bus for use in control algorithms, display, alarming, and data logging. The HART communication circuitry superimposes digital HART signals on the analog current loop, enabling bidirectional communication with HART-enabled field devices. The module continuously monitors each channel for faults such as open circuit, short circuit, or out-of-range conditions, and reports these faults to the controller. Redundant modules operate in parallel, with automatic switover if the primary module fails.
