Description The Model FL645 RTD Isolation Amplifier conditions a resistance input from an RTD temperature probe. RTD resistance varies with temperature, producing a DC output voltage from the FL645. The input is isolated from the output by up to 1000VDC. The unit is mechanically and electrically compatible with Encore's other FlexiLine DIN-rail mounted instrumentation.
