max source current
Resistance: Current mode: 500 ohms maximum load
Signal: Field selectable 0 to 5V, 0 to 10V,
0 to 20, 2 to 10V, mA, 4 to 20 mA

All models contain on-board electronics and calibration curves that provide a linear signal output. This linear signal is sent out as either a current (mA) or a voltage (V) signal, allowing output to a variety of data loggers or data acquisition systems. In addition, the current and voltage output ranges are user-selectable for your convenience.
