VE4003S2B10 16‑Channel 4‑Wire AI Terminal Block for Series 2 Plus
VE4003S2B10 is a dedicated 16‑channel 4‑wire analog input terminal block for Emerson DeltaV M‑series Traditional I/O subsystem. It is designed exclusively for AI Plus 16‑channel 4‑20mA HART I/O card. VE4003S2B10 acts as signal transition hardware between field 4‑wire transmitters and I/O cards. Pre‑wiring can be completed on cabinet side before I/O card installation. Hot‑swap of I/O card is allowed without field wiring modification. VE4003S2B10 adopts unique keying mechanism to prevent mismatched card insertion. Combined with M‑series I/O carrier, VE4003S2B10 establishes complete analog input interface for DeltaV distributed control system.

Core Advantages
- Support pre‑construction field wiring. All field cables can be terminated on VE4003S2B10 in advance. I/O cards can be fitted later during commissioning phase, shorten site work cycle and avoid card damage during construction period.
- Unique A6 key lock mechanism. VE4003S2B10 only accepts A6 key position AI Plus 16‑channel card, avoid human error of wrong card replacement during maintenance work.
- Native support for external powered 4‑wire transmitters. Field power is supplied from external source instead of internal I/O card loop, deliver stable signal acquisition for high‑power 4‑wire smart instruments.
- Full HART protocol pass‑through, preserve HART digital message without attenuation. Transmitter diagnostic data and parameter can be retrieved by DeltaV and AMS device management platform.
- Rugged industrial environment adaptability, G3 conformal coating and wide operating temperature range. It meets hazardous area Zone2 installation requirement for petro‑chemical plants and offshore facilities.
Product Features
VE4003S2B10 is an I/O interface component. Full I/O unit requires pairing with AI Plus 16‑channel 4‑20mA HART card, it cannot run independently.
HART pass‑through function, typical HART scan time for each enabled channel ranges 600‑800ms.
Field pre‑wiring is allowed. I/O card supports hot‑swap under power within safe non‑hazardous area.
This simplex terminal block does not support redundant I/O pair installation. For 1:1 redundancy application, select VE4033S2B10 redundant terminal block.
Certifications: CE, FM, CSA, ATEX, IEC‑Ex, marine IACS E10 for offshore project deployment.
Screw type terminals accept standard stranded and solid signal cables.

Sourcing & Selection Guidance
- Confirm I/O card model. VE4003S2B10 is only compatible with AI Plus 16‑channel card. Standard 8‑channel AI card cannot pair with VE4003S2B10.
- Confirm field transmitter wiring type. Select VE4003S2B9 for 2‑wire transmitters; choose VE4033S2B10 if I/O redundancy is required.
- Check DeltaV software revision. VE4003S2B10 requires system software v13.3.1 or newer. Older firmware cannot recognize Plus‑series I/O interface.
- Verify carrier hardware: VE4003S2B10 fits M‑series carrier only. Physical incompatibility exists with S‑series carrier.
- For mass‑termination cabinet layout, replace VE4003S2B10 with 48‑pin mass terminal VE4003S2B11.
Pitfall Reminders & After‑sales Notes
Pitfall1: VE4003S2B10 is terminal block only, without I/O card. Many orders only place VE4003S2B10 and miss AI Plus card, leading to no signal acquisition on‑site.
Pitfall2: VE4003S2B10 cannot mount onto S‑series carrier. Never mix M‑series and S‑series I/O carrier hardware.
Pitfall3: Software version must be v13.3.1 or above for Plus‑series I/O hardware support.
Pitfall4: No built‑in channel fuse inside VE4003S2B10. External fuse is required for loop protection, or select mass‑termination solution.
Pitfall5: For hazardous area installation, strictly follow Zone2 installation manual. Hot‑swap is forbidden in explosive hazardous zones.
After‑sales: For hardware fault check carrier condition, software version and card keying match status first. For wiring issue, verify screw torque. Provide full part number VE4003S2B10 for spare‑part application, confirm Series2 Plus hardware revision.
Frequently Asked Questions
Q: Can VE4003S2B10 work standalone without I/O card?
A: No. VE4003S2B10 is terminal hardware only. Complete I/O interface requires both VE4003S2B10 terminal block and AI Plus 16‑channel I/O card. Analog input cannot be captured without corresponding I/O card.
Q: Can VE4003S2B10 connect with 2‑wire transmitters?
A: Not recommended. VE4003S2B10 is optimized for externally powered 4‑wire transmitters. Select VE4003S2B9 terminal block for 2‑wire field instruments.
Q: Is VE4003S2B10 compatible with DeltaV v12 software?
A: Not supported. VE4003S2B10 belongs to Plus‑series I/O family, minimum required DeltaV software version is v13.3.1.
Q: What is difference between VE4003S2B10 and VE4033S2B10?
A: VE4003S2B10 is simplex (non‑redundant) terminal block. VE4033S2B10 is redundant terminal block which accepts dual AI Plus cards to achieve 1:1 I/O redundancy for critical process loops.
Q: Can VE4003S2B10 install on S‑series I/O carrier?
A: Physically incompatible. VE4003S2B10 supports M‑series I/O carrier only. M‑series and S‑series carriers cannot be interchanged.
Q: Does VE4003S2B10 support HART communication? Is extra hardware needed?
A: HART pass‑through is built‑in without extra hardware requirement. Just enable HART function for relevant channel inside DeltaV software to access transmitter diagnostic and HART variables.
Q: Does VE4003S2B10 terminal block integrate channel fuses?
A: VE4003S2B10 does not contain internal fuses. External fuse component must be added for circuit protection. Choose mass‑termination blocks for fused layout.
Q: If I already own VE4003S2B10, can I just add a second AI Plus card to implement I/O redundancy later?
A: It cannot be done this way. Simplex VE4003S2B10 hardware cannot hold dual I/O cards. Terminal block must be replaced with VE4033S2B10 redundant terminal block before adding secondary AI Plus card.

Important Notes
- VE4003S2B10 is terminal assembly only. Make sure corresponding AI Plus I/O card part number is included in purchasing list.
- Separate field power circuit and signal circuit for 4‑wire transmitters. Never connect external power supply into signal terminals, hardware damage will occur.
- A6 keying position of VE4003S2B10 cannot be modified. Forcing unmatched I/O card insertion causes permanent mechanical damage.
- Long‑term continuous operation under maximum high ambient temperature shortens service life of I/O assembly. Ensure cabinet ventilation and heat dissipation.
- Hot‑swap I/O card operation applies to safe non‑hazardous location only. Power‑off procedure is mandatory for hazardous Zone2 environment following installation guideline.
- HART communication performance relates to field cable length, wiring must comply with DeltaV official HART wiring specification.
