Performance Parameters: High measurement linearity in full 4-20mA input range. Low temperature drift ensures stable measurement for long-time running. Strong noise filtering ability for industrial field analog signal. High channel isolation performance to reduce cross-talk interference.
Material Composition: FR4 industrial printed circuit board. High precision ADC chips. Analog signal filtering and conditioning components. TVS surge suppression devices. Flame retardant plastic front panel with LED indicators. Gold plated backplane edge connector.
Structural Features: DeltaV S-series plug-in module form factor. Front panel fitted with LED indicators for power, running and fault state. Internal circuit partition for analog input front end and digital processing part. Edge connector links to rack backplane for power and LocalBus communication. Equipped with extraction handle for module disassembly. Match dedicated terminal block for field transmitter wiring.
Working Principle: 4-20mA analog signal from field transmitters enters module through supporting terminal block. Signal conditioning circuit filters and conditions input current signal. ADC chip converts analog signal to digital value. Digital data is transmitted to DeltaV controller via LocalBus backplane. Onboard diagnostic circuit continuously checks signal range, judges wire break or abnormal signal and reports fault information to DeltaV workstation.
Installation Requirements: Insert VE4003S5B1 into specified slot inside DeltaV I/O rack. Install matched terminal block and connect field transmitter shielded cables. Use shielded twisted pair cable for all analog input wiring. Separate analog signal cables and power cables in different cable ducts. Install rack in ventilated IP20 control cabinet. Complete protective earth bonding of rack chassis.
Usage Notes: Set engineering unit scaling parameters in DeltaV configuration software during commissioning. Verify transmitter loop power supply and wiring polarity before power on. ESD protection is required before touching circuit board. Hot swap operation is available for module replacement. Check terminal connection tightness periodically in vibration environment.
