general description
tk5000 signal isolator is a card-mounted instrument of modular structure. it converts the 4 ~ 20ma dc c（or 1~5v dc）signals to the isolated 4 ~ 20madc (or 1 ~ 5v dc) signal output, which is supplied to indicator, recorder, analog regulator, programmable single / multiple loop digital controller, industrial process controller and distributed systems, so that they form variety of monitoring and control system. the power supply, input and output of the processor are isolated from each other, and the processor is an indispensable instrument forming non-explosion proof automatic control system.
