Product Description:
JK208 acquisition module is composed of host JK200 and data acquisition module JK208T JK208T acquisition module adopts 24-bit high precision AD sampling chip, the accuracy can reach 5 ‰, differential isolation technology, so that the sampling is more stable, more accurate. The channel type supports arbitrary switching of thermal resistance signal, thermocouple signal, current signal and voltage signal. The number of channels can be combined freely, and a maximum of 256 channels can be collected simultaneously .
Application field:
JK208 acquisition module is widely used in industrial automation equipment, and precision automation system to collect relevant data
