SCC402 is a 3-port signal isolator developed specifically to measure AC and DC voltage/current and generate an isolated current or voltage output. It is available in a 23mm snap-on enclosure for 35 mm DIN 46277 rail mounting. This isolator has exceptionally high accuracy and stability. SCC402 provides isolation between its own power supply, the input and output signals up to 1.5 KV AC RMS per minute and 250 V AC RMS continuously. The operator calibrates Zero and Span for the isolator via multiturn potentiometers.
