Introduction
The TB-2605 is an isothermal terminal block that consists of a printed
circuit board with screw terminals. The terminal block connects directly
to the front panel I/O connector of the NI 2501 or NI 2503.
The terminal block can easily accommodate thermocouples, resistance
temperature detectors (RTDs), thermistors, and voltage signals.
The TB-2605 features an isothermal construction to minimize the
temperature gradients across the screw terminals and a high-accuracy
thermistor cold-junction temperature sensor for measuring with
thermocouples. Enclosures keep out air currents to maintain an isothermal
environment for the screw terminals and the cold-junction sensor.
