Analog Output

The BU-905U-L-R module provides a 4 - 20mA DC analog output for connecting to instrument indicators to display remote analog measurements. The analog output is a current source provided from an internally generated +24V loop supply.

When connecting to an external device (e.g. electronic indicator, recorder, PLC / DCS input, etc.) by connecting the output between the Analog Output terminal (+) and the COM terminal (-).

Note: Zener protection of analog outputs provides protection against short periods of over-voltage; however longer periods may result in module damage.

You can also individually configure analog outputs to turn off (i.e., 0mA) if no command message is received to the output for a certain period.

The following diagrams illustrate different connection methods:
