Overview

Product overview

Key product information and technical features.

The CFP-CB-1 is a wiring accessory, not an acquisition or signal-conditioning I/O module. NI identifies it as a general-purpose connector block suitable for Compact FieldPoint I/O modules.

Its 36 terminals simplify field wiring by avoiding the need to connect multiple wires to one terminal. Strain-relief provisions help secure wiring in applications subject to shock and vibration.

  • General-purpose connection for Compact FieldPoint I/O modules.
  • 36 field-wiring terminals.
  • Strain-relief bar and separate wire-tie connector.
  • V and C terminals for supply and common connections.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the CFP-CB-1 an eight-channel I/O module?

No. NI identifies it as a 36-terminal connector block for Compact FieldPoint I/O modules.

Where are signal assignments defined?

Use the connected I/O module's operating instructions. Check the block's numbering because earlier versions differ.

Which connector block does NI recommend for thermocouples?

NI recommends the isothermal cFP-CB-3 for the most accurate cold-junction compensation.
