SC99: Signal Converter 2 Channels

- Selectable DC. Voltage or DC. current input

- Two isolated channels

- Isolated input, output and power supply

- Plug-in socket structure

            Signal Converter SC99 accepts any standard input signals and converts to two isolated outputs signals. Low input resistance to current signals and high input resistance to voltage signals mean the signal converter can be inserted into existing system with no loss of performance. To minimize noise and other signal errors, the Signal Converter also features complete galvanic isolation of input, output and power supply.
