Loop-Powered Digital Indicators in Panel-Mount Housing
Digital loop-powered 830 series indicators are universally useable in current measurement circuits; switching (either 0 … 20 mA or 4 … 20 mA) is simply performed via the terminals. The measured value is displayed for a current as low as 0.3 mA. Thanks to the low voltage drop of just 0.5 V, the use in current loops with a low load voltage is also possible.
