Emerson VE4002S1T2B3 DeltaV Analog Input Module
Configured for 4-20 mA field signal acquisition in DeltaV S-series architectures, the Emerson VE4002S1T2B3 (VE4002S1T2B3 Analog Input Module) provides direct physical/electrical execution. The module digitizes analog current loops via 16-bit analog-to-digital converters, transmitting process variables directly to the central system controller across the local bus interface.

4-20 mA HART Loop Protocol and Channel Isolation
The VE4002S1T2B3 integrates dedicated channel-to-channel galvanic isolation across all 8 input paths, preventing ground loop currents and suppressing common-mode voltage spikes in distributed field wiring. The internal signal processing hardware supports the 4-20 mA HART loop protocol via point-to-point pass-through communication, allowing higher-level asset management software to extract digital diagnostic and configuration parameters directly from smart field transmitters without interrupting primary analog control signals.
Frequently Asked Questions
Q: Does the VE4002S1T2B3 support multi-drop HART network topologies?
A: No. The onboard HART communication hardware operates strictly in point-to-point pass-through mode, dedicated to single-device channel loops.
Q: How does channel-to-channel isolation benefit the module in harsh electrical environments?
A: Galvanic isolation breaks ground loops between separate transmitter loops, preventing electrical noise on one channel from interfering with adjacent analog measurements.
Q: What environmental protection levels are implemented on the circuit assembly?
A: The module conforms to ISA-S71.04 Class G3 requirements for airborne contaminants and carries an IP20 mechanical ingress rating.
Field Installation Guidelines
Mount the VE4002S1T2B3 module directly onto the designated DeltaV S-series I/O terminal block carrier until the retention latch snaps firmly into position. Route all 4-20 mA field wiring through shielded twisted-pair cables, ensuring signal cables remain physically separated from high-voltage AC power lines to avoid inductive noise coupling. Terminate cable shields at the central cabinet ground bar using a single-point connection. For installations operating in Class I Div 2 or Zone 2 hazardous locations, verify that the external cabinet maintains an IP54 or equivalent enclosure rating prior to energizing the 24 VDC field circuit.
