Part number VE4001S2T1B1 is listed by Emerson as 8-Channel 24 V DC Isolated Discrete Input with Standard I/O Termination Block.
VE4001S2T1B1 belongs to the Emerson DeltaV M-series Traditional I/O hardware family. Its exact ordering suffix defines the electrical function and termination arrangement; selection must be based on the full model, not on physical appearance alone.
Purchasing check: Lifecycle status is separate from exact product identification. Confirm current orderability, supported hardware revision, condition and lead time with Emerson or the sales team.
Important: Approve replacements only after the full model, hardware revision, carrier or termination arrangement, field power and site requirements have been checked.
Use the following checks to confirm that the exact VE4001S2T1B1 configuration fits the installed DeltaV system.
Match the isolated-input function, standard terminal block keying, field voltage and channel wiring before installation.
Technical basis: Emerson DeltaV M-series Traditional I/O Product Data Sheet, March 2026
It is the eight-channel 24 V DC isolated discrete-input configuration; confirm each device can meet the greater-than-10 V on threshold and less-than-5 V off threshold.
Yes. Emerson specifies optical isolation from the system and between channels, factory tested to 1500 V DC.
No field-circuit power is provided by this card configuration; engineer the external 24 V DC field supply and protection separately.
The official specification states 5 mA at 24 V for the isolated input.
No automatic substitution should be made. The isolated-input electrical behavior, wiring and terminal-block key differ and must be reviewed.
Use 75 mA typical and 100 mA maximum at 12 V DC nominal for the engineering power-budget check.
The I/O interface plugs into an M-series I/O carrier, and the function-key system must match the correct terminal block before insertion.
Check IP20 enclosure protection, -40 to 70 °C operating temperature, non-condensing humidity and ISA G3 airborne-contaminant requirements.
Verify polarity, channel assignment, field-supply commoning, terminal torque, keying, shield and grounding practice, and that no channel exceeds the documented input limits.
Ask for the complete model and revision, clear nameplate and connector photographs, terminal-block type, quantity, condition and compatibility confirmation.
