Description
Emerson VE4003S3B1
Technical Specifications: Model: VE4003S3B1 Channel number: 8 analog input channels Input signal: 4-20mA current signal ADC: High resolution analog to digital converter Backplane bus: DeltaV LocalBus Power supply: 24VDC from rack backplane Operating temperature: 0℃ to +60℃ Storage temperature: -20℃ to +70℃ Relative humidity: 5% to 95%, non-condensing Protection class: IP20 Mounting: Plug-in card for DeltaV I/O rack
Functional Features: Collect 4-20mA analog signals from pressure, flow, level and temperature transmitters. High precision analog-to-digital conversion for process measurement values. Built-in wire break detection for field transmitter loops. Surge and overvoltage protection on each input channel. LED indicators on front panel to show module operation and fault status. Support hot swap online replacement without powering off rack. Upload process values and diagnostic alarms to DeltaV controller.
Application Scenarios: Chemical continuous production process monitoring, natural gas processing plant parameter acquisition, power station auxiliary system measurement, pharmaceutical plant process parameter collection, food and beverage factory temperature and pressure supervision.
Performance Parameters: High measurement accuracy across full 4-20mA range. Low thermal drift for stable long-term measurement. Effective suppression of common-mode noise from field wiring. Low channel cross interference between different input channels.
Material Composition: FR4 high quality printed circuit board. High precision ADC chips. Analog filter and signal conditioning components. Surge protection semiconductor components. Flame retardant plastic front panel with LED lamps. Gold plated edge connector for rack backplane.
Structural Features: Standard DeltaV S-series plug-in card design. Front panel equipped with power, run and fault LED indicators. Internal circuit separates analog signal front end and digital bus circuit. Edge connector realizes power supply and LocalBus communication with rack backplane. Built-in extraction handle for convenient module maintenance. Work with dedicated terminal block for field cable termination.
Working Principle: Field 4-20mA current signal flows into module through matched terminal block. Analog conditioning circuit filters noise and adjusts signal level. ADC converts analog signal to digital data. Digital data is delivered to DeltaV controller via rack LocalBus. Onboard diagnostic circuit monitors signal value range continuously. When wire break or signal out-of-range occurs, module sends fault alarm to DeltaV system.
Installation Requirements: Install VE4003S3B1 to the assigned slot of DeltaV I/O rack. Mount supporting terminal block and connect shielded field transmitter cables. Use shielded twisted pair cable for analog signal wiring. Keep analog cables separated from high voltage power cables. Install rack in ventilated IP20 electrical cabinet. Complete protective earth connection of rack chassis.
Usage Notes: Configure scaling and filter parameters in DeltaV configuration software during commissioning. Check wiring polarity and loop resistance before power energization. Wear anti-static wristband when handling module. Module can be hot swapped online without rack shutdown. Check cable insulation and terminal tightness regularly.
