aAs the number of old people has reached 18% of the population, there is a pressing need in Nanjing market for the coming of rehabilitation agencies with international advanced experiences. As Orpea’s first project in China, Nanjing has made the first move in the industry and got a high ...
For this reason, the standard module implementation has a channel density that is typically limited to only four or eight channels, with only hundreds of volts of channel-to-channel isolation. This article will briefly discuss isolation in the process control analog input module and th...
