More Information

Overview Manuals Specifications Input Review Wiring Review System Matching

Features:

  • Eight isolated inputs: Each channel is optically isolated from the system and from the other channels.
  • Defined switching levels: The documented on threshold is above 10 V DC and the off threshold is below 5 V DC.
  • Standard termination: The exact order code includes the standard I/O termination block for the isolated DI card.

VE4001S2T1B1 is an order-specific DeltaV M-series I/O assembly combining the documented card function with the listed termination block.

Engineering review should match the signal type, channel count, card keying, terminal block, controller, carrier, and required DeltaV software level.

Procurement should compare the complete VE4001S2T1B1 code with the installed label because adjacent table rows describe materially different termination options.

Availability is subject to Apter Power's current inventory and sourcing confirmation.
