16 Channel-To-Channel Isolated Ai Solution For High End TC/RTD Modules

Overview

plc-ai-solution_en

Due to strict robustness requirements, channel-to-channel isolation is a common requirement for analog input modules in many applications such as gas and oil plants and power plants. This is especially true for thermocouple/RTD modules, whose small signals are susceptible to noise and where the bare sensing element may be exposed to high common-mode voltages. This article will outline a high density, easy to design, channel-to-channel isolation solution for analog input modules. Test results are included and verified that a 16-channel, 2.5 kV rms channel-to-channel isolation demo could easily pass the EN55022 class B standard.
