Technical Specifications: Model: VE4003S2B6 Channel quantity: 8 analog input channels Input signal: 4-20mA ADC resolution: High precision analog to digital conversion 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: Receive 4-20mA analog signals from various field process transmitters. High precision conversion from analog current signal to digital engineering value. Automatic detection of transmitter loop open circuit and abnormal signal. Built-in overvoltage and surge protection for each input channel. Front panel LED indicators for module running state and fault warning. Hot swap function supports online replacement without rack power off. Transmit real-time process data and diagnostic information to DeltaV controller.
Application Scenarios: Refinery process parameter monitoring, petrochemical reactor measurement, power plant boiler and turbine auxiliary parameter collection, offshore oil platform process supervision, waterworks flow and pressure measurement, cement factory kiln parameter monitoring.
Performance Parameters: High linearity measurement in full 4-20mA signal range. Low temperature drift for long-term stable measurement. Strong ability to reject common mode interference in industrial environment. Low cross-talk between different input channels.
Material Composition: FR4 industrial printed circuit board. High precision ADC chips. Analog signal filtering and conditioning circuit components. TVS surge suppression components. Flame retardant plastic front panel with LED indicators. Gold plated edge connector for backplane connection.
Structural Features: DeltaV S-series plug-in I/O card structure. Front panel with power, run and fault LED status lights. Internal circuit zoning for analog input front end and digital processing area. Edge connector connects to rack backplane for power and LocalBus communication. Equipped with extraction handle for easy disassembly. Cooperate with dedicated terminal block for field wiring termination.
Working Principle: 4-20mA signal from field transmitters enters module through matched terminal block. Analog conditioning circuit filters noise and adjusts signal level. ADC chip converts analog signal to digital data. Digital measurement value is sent to DeltaV controller through LocalBus backplane. The diagnostic circuit monitors signal state continuously and reports wire break or signal abnormality to DeltaV workstation.
Installation Requirements: Insert VE4003S2B6 module to designated slot of DeltaV I/O rack. Install matching terminal block and connect shielded twisted pair field cables. Separate analog signal wiring and high-power cables. Mount rack in ventilated IP20 control cabinet. Complete protective earth bonding of rack chassis.
Usage Notes: Set range and engineering unit scaling in DeltaV configuration software during commissioning. Check transmitter loop power supply and wiring polarity before power on. Use ESD protection measures when touching module circuit board. Online hot swap is available for module replacement. Inspect terminal tightness and cable sheath condition regularly.
