The Analog Input module is available in three versions: unipolar, bipolar and current. The unipolar
module covers the voltage range, 0 to +10 V. The
bipolar module covers the voltage range, - 10 to +1 0
V. The current module accepts currents in the range,
4 to 20mA;with a simple change of front panel connections it reads voltages in the range, +1 to +5 V.
The Analog Input module features and benefits are
summarized in Table 1.
