7.0 ANALOG (TRANSDUCER) OUTPUT OPTION
7.1 Introduction
The Transducer Output options (0 -1 mA or 4-20 mA) feature 3 separate outputs each
with two terminals, one of which is common to all three outputs and one which
provides a unique return path for each output.
7.2 Specifications
Outputs: 3 bi-directional, 0-1mA (active) or 4-20mA (loop powered, passive)
0 – 1mA Current Range
Output Range: 0 to +/-1mA into 10K ohms or less; Overload to
+/-2.1mA into 5K ohms or less.
Resolution: 0.22uA

Data Update Rate (poll rate): 100ms minimum
7.3 Connections
The connections for the 0-1mA output option are shown in figure 9, while the
connections for the 4-20 mA with external and internal loop are shown in figure 10.
