Analog Output

The optional analog output module gives the LevelCom 100 a 4 – 20 mA output capability.

The output can function either as a gauge output to remotely indicate depth, volume, or

weight to a remote meter, or data acquisition system. If the LevelCom 100 has the auto

specific gravity option installed the analog output can also function as a specific gravity

gauge output.

It is also possible to configure the analog output as a control output. In this case there are 4

adjustable parameters to configure the output value. The Minimum Current is a value

between 4 mA and 20 mA. The maximum current is a value between the minimum current

value and 20 mA. The Minimum Current Setpoint is the depth where the output signal takes

the minimum value. The Maximum Current Setpoint is the depth where the output signal

takes the maximum value. This gives great flexibility in the configuration of the analog

output.

If the Minimum Current Setpoint is below the Maximum Current Setpoint, the current will be

at the Minimum Current value when the level is below the Minimum Current Setpoint. The

output will vary smoothly from the Minimum Current value to the Maximum current value

when the level is between the setpoints. When the level is above the Maximum Current

Setpoint, the output current will remain at the Maximum Current value.

If the Minimum Current Setpoint is above the Maximum Current Setpoint, the current will be

at the Maximum Current value when the level is below the Maximum Current Setpoint. The

output will vary smoothly from the Maximum Current value to the Minimum current value

when the level is between the setpoints. When the level is above the Minimum Current

Setpoint, the output current will remain at the Minimum Current value.
