General Description
TK5000 distributor is a card-mounted instrument of modular structure. It provides isolated power supply to the scene of two-wire transmitter. At the same time, the 4 ~ 20mA DC signals from two-wire transmitter is converted 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. It is widely used in the detection and control systems in the industrial process. The processor is an indispensable instrument forming non-explosion proof automatic control system.
