The Demico Battery Transducer is a unique Transducer which is powered from the battery it is monitoring, eliminating the need for an additional power source. This transducer is calibrated across the upper half of the maximum specified input voltage and the output is an isolated current source which is linearly proportional to the input Voltage. A simple resistor from 0 to 10,000 ohms is all that is required to scale and interface to a standard RTU analog input. The transducer output’s galvanic isolation from the battery eliminates ground loops and ground referenced noise.
Two output options are available. The BA_11 series 0 to 1mA output is scaled from zero to maximum Input Voltage. The BA_12 series output is scaled across the upper half of the input range. See the output charts and graphs at the links for the individual models in the chart below.
