4-20 mA Current Output

Operating in this mode, any 3000 Series instrument can transmit high-accuracy measurement data as process signals for supervisory monitoring and control.

Each "C" unit produces two kinds of analog output simultaneously: (1) its normal voltage output and (2) a current output continuously proportional to the voltage signal to within ±0.05%.

As normally shipped, this option generates a current output within the ISA standard signal range of 4 to 20 mA, corresponding to a range of 0 to +5 V.  Bipolar ranges of ±16 mA and 4 to 12 to 20 mA are also available, each corresponding to -5 to +5 V.  Voltage compliance is +5 V relative to Signal Common.

NOTE: The "C" Option may NOT be used in combination with the "G," "P," "R," or "S" Option.
