GENERAL DESCRIPTION
5 Digits (99999), 0.5” High, Display updates once Featuring 5 digits of rate and 8 digits of total, the HIT-2A is a DC, AC, loop or battery powered indicator capable of accepting magnetic pickup, DC pulse or switch 10 segment bar graph display for rate trend. closure inputs. The unit can be ordered with an optional loop powered 4-20mA output. The HIT-2A uses the 4- TOTALIZER DISPLAY: (SELECTABLE DECIMAL)
20mA loop to provide power when this output is used. Totalizer Descriptors: GAL, LIT, FT3, M3, BBL SPECIFICATIONS
Power Supply:
