Phoenix Contact 3100047 Thermoelectric Voltage Terminal Block Pair
The Phoenix Contact MTKD-FE/CUNI EX terminal block pair (part number 3100047) is a specialized component designed for extending thermocouple equalizing conductors within measuring circuits. These terminal blocks are crucial for maintaining accurate temperature measurements in industrial applications where thermocouples are used. The equalizing conductors are constructed from materials that mimic the thermal characteristics of the corresponding thermocouples up to temperatures of 200°C, ensuring minimal measurement errors. The terminal block offers a robust screw connection for secure conductor termination, supports a nominal voltage of 400V and a nominal current of 1A, and is compatible with various NS 35 mounting rails. Its robust construction and compliance with industry standards make it suitable for demanding industrial environments.
