Scale Card Safe Area Hazardous Area Loop powered 2-Wire 4 to 20mA 4 digit indicator Zener barriers or galvanic isolators The HBS307E is a loop-powered 4 digit lcd indicator used to display a measured variable in customer selected engineering units within a hazardous area. The zero and span of the display are independently adjustable allowing the indicator to be calibrated to display any linear variable represented by the 4 to 20mA signal. The scale card can easily be marked to show the units of measurement and be installed on-site without dismantling the indicator enclosure or removing it from the panel. A bold 15mm high 4 digit display provides maximum contrast and has a very wide viewing angle, allowing the indicator to be read easily in most lighting conditions over a wide temperature range. The four digits, with three decimal points and a negative sign, may be configured to display any variable between -9999 and 9999.
