For analog output, interference prevention is Interference Prevention not possible. Weight Approximately 75g 1. Analog current output specification is based on the power voltage range from 12 to 24V DC (10%). Use the attached resistor (249, 1/4W) as a load resistance for converting analog output to voltage. 2. Response time for analog current output is between 10% and 90% of the rise or fall of the voltage signal when using a 249 resistor.
