Emerson SE4307T01 DeltaV Intrinsically Safe Analog Input CHARM
The Emerson SE4307T01, also cataloged as the SE4307T01 Intrinsically Safe Analog Input CHARM, operates as a dedicated hardware component for hazardous-area 4-20 mA current loop acquisition within Emerson DeltaV Electronic Marshalling platforms. The card digitizes incoming field signals via a 16-bit analog-to-digital converter while providing integrated galvanic separation without requiring external interposing isolation barriers.

4-20 mA HART Loop Protocol and Channel-to-Channel Isolation
The SE4307T01 routes primary variable data while executing digital HART v7 pass-through communication across the system backplane. Channel-to-channel galvanic isolation compliant with EN 60079-11 eliminates parasitic ground loops and protects backplane logic from field-side voltage spikes up to 375 VDC peak. The onboard power controller drives 2-wire transmitters at >=16 V under a full 20 mA load, maintaining dynamic HART multi-drop and secondary variable passthrough directly into AMS device management software.
Frequently Asked Questions
Q: Does the SE4307T01 require separate external intrinsic safety barriers when wired to Zone 0/1 transmitters?
A: No. The SE4307T01 integrates EN 60079-11 intrinsically safe isolation directly into the CHARM circuitry, permitting direct termination of field cables from hazardous areas.
Q: How does the CHARM respond when a field device generates current above the nominal 20 mA range?
A: The input circuitry processes full-scale signals up to 22 mA before clipping, allowing continuous over-range measurement and NAMUR NE43 fault diagnostic tracking.
Q: Can an engineer hot-swap the SE4307T01 CHARM on an active CHARM I/O Bus (CIOC) baseplate?
A: Yes. Individual CHARMs support hot-swapping on a powered baseplate without interrupting adjacent CHARM channels or corrupting backplane communications.
Field Installation Guidelines
Insert the SE4307T01 CHARM directly into its assigned slot on the DeltaV CHARM terminal block base until the mechanical retention tab locks securely. Verify that field wiring connections strictly comply with local Intrinsically Safe (Ex i) installation standards, maintaining physical separation between IS field conductors and non-IS power circuits. Ground all shielded twisted-pair signal cables at the designated single-point system earth busbar before applying 24 VDC main power to the CIOC carrier.
