Chapter 1.0Analog Output Kit OptionThe Analog Output option kit provides an isolated 4-20 mA or 0-10 VDC analogsignal output for displayed weight, gross weight or rate (if enabled in setup). Theanalog output uses a 16-bit D/A converter for a very precise output. The outputsignals will be at the lower limit (0 VDC or 4 mA) when the value represented is atzero. When the value reaches its maximum limit, the output signal will increase tohigher limit (10 VDC or 20 mA). Any value between zero and the maximum limitwill be represented as a percentage of the output proportional to the percentage ofthe value.The Analog Output sub-block lets you select the data source for the analog signaland provides a method to calibrate the analog zero and high limit values. TheIND560 terminal must be calibrated to the desired scale capacity before makingAnalog Output adjustments. If rate is to be used as the source for the analog outputsignal, it must be enabled in the Scale Rate branch of setup. The Analog Outputcard provides one channel - it may be either current (4-20 mA) or voltage (0-10VDC).SpecificationsMaximum Cable Length:0-10 VDC – 50 ft (15.2 m)4-20mA – 1000 ft (300 m)Min/Max Load Resistance:0-10 VDC – 100k ohms minimum4-20 mA – 500 ohms maximumOutputs:1 channel capable of supplying 4-20 mA or 0-10 VDCResolution:16 bit resolution - 65536 levels across entire rangeNote that if the load resistance ratings are exceeded, the analog output will notoperate properly.1-1
