Overview

Product overview

Key product information and technical features.

The CFP-CB-3 provides field-wiring connections rather than functioning as a standalone acquisition module. Its isothermal construction minimizes temperature gradients at the thermocouple terminals.

A built-in thermistor supports cold-junction compensation. NI recommends this connector block for thermocouple measurements where increased accuracy is important.
