There are 4 analog inputs (4 to 20 mA, 0 to 20 mA, or 0 to 1 mA) that may be used to
monitor transducers such as vibration monitors, tachometers, pressure transducers, etc.
These inputs may be used for alarm and/or tripping purposes. The inputs are sampled
every 50 ms. The level of the analog input is also available over the communications port.
With the EnerVista 489 Setup program, the level of the transducer may be trended and
graphed.
