Dewesoft IOLITEir-8xTH-HS high-speed thermocouple module

The IOLITEir-8xTH-HS is an updated version of the Dewesoft 8-channel IOLITE thermocouple temperature module. It’s a channel-to-channel isolated DAQ device for thermocouple temperature measurements using universal thermocouple inputs: K, J, T, R, S, N, E, C and B.

The device addresses the need for stable temperature measurements in EMC-harsh environments, such as on the stator of an electric motor or near inverters. The module not only improves the EMC immunity of the previous unit on the digital side but also utilises a sharp analog antialiasing filter (3rd order, -3 dB @ 1 kHz) and digital FIR filters to remove unwanted frequencies.

The input connector of the module is MINI TC for the universal thermocouple type. It offers sensor break detection in the software and applies physical LED indicators.

The module uses a 24-bit ADC with sampling rates up to 10 kS/s per channel, enabling the IOLITEir-8xTH-HS to be used in dynamic and demanding applications to record transients of temperature shock.

A higher sampling rate enables Dewesoft filtering technology using digital FIR filters to reduce the noise floor down to -130 dB and reach a resolution of less than 1 μK.

The IOLITEir-8xTH-HS is equipped with two EtherCAT buses in parallel for both DAQ and real-time control.
