The VTD-BD series voltage transducer senses voltage in dc-powered installations. It is applicable for use on circuits to 600 Vdc. It provides a fully isolated ±5 Vdc or ±10 Vdc output signal in response to dc voltages that change polarity. It is housed in an easy-to-install DIN rail- or panel-mount case and is available in a variety of ranges to suit many primary voltages. Features include six ranges of input voltages from ± 0-15 to ±0-600 Vdc and input/output isolation for improved safety of use.
