The design and construction of the input and output isolation system for power channel and control rod position in the research reactor SR4 with analog device AD210

The design and construction of analog input-output system with device AD210, SR4 (ICS Kartini Reactor) is used as interface and output signal isolation system for power channel meter NLW-2, NP1000 and control measurement with the slave computer system so that the measuring tools and computer operate independently. Device AD210 provides a very compact insulators and economically with highly accurate system performance. It is a DIP chip with 3-port model, input, output and integrated power supply. It can be applied as a multichannel data acquisition, or a single channel and others. Analog Device AD210 is placed between the output channel power measurement and control rod position measurement system / other support tools such as Computer Slave, ADC, multiplexer, and others. The design and construction of Analog Devices AD210 insulator use the input-output mode with the gain of 1, so that pulses or output voltage are equal to the input voltage pulses. The test results in graphs of output versus input are excellent with the linearity close to 100%. The use of this Device AD210 for NLW2 and NP1000 which are a vital instrument for the continuity of the operation of reactor, is expected to increase the Main Time Between Failure (MTBF) of the reactor as a whole.
