Weidmüller WDU 2.5/TC TYP K (Order No. 1024100000) is a dark beige thermocouple terminal block for Type K thermocouples, rated at 2.5 mm² cross-section and 55 V, certified to IECEx/ATEX for 55 V / 8 A (Ex eb II C Gb, II 2 G D). It offers 2 screw-connected connections across 1 level with 2 clamping points per level and requires an end cover plate. Mounted on a TS 35 rail, it measures 10.2 x 60 x 50 mm (W x H x D) and weighs 15.54 g. The ambient temperature range for this model is -5–40°C, and it is not offered as an explosion-tested version.
Thermocouple terminal blocks are specially designed for the transmission of very small voltages in temperature measuring circuits: special current bars ensure that no false signals are transmitted within the terminal block when temperature differences exist between the positive and negative paths, a level of measuring precision required, for example, in aircraft engine test rigs, complicated chemical processes, and controllers. This model is made from Wemid material with a UL 94 V-0 flammability rating and is RoHS compliant.
