If you continue scrolling the list repeats with a “4” appearing in the

line above the parameter indicator to designate a 4 to 20 mA output.

Analog Output Connections

Connections to all analog outputs (1 to 6, depending on the option)

are made via a 9-pin D-sub connector. The female socket is on the

rear panel. A matching male connector with a patch cable is used for

external connections. Pin assignments are as follows:

Output 1 Pin 1 Output 2 Pin 2

Output 3 Pin 3 Output 4 Pin 4

Output 5 Pin 5 Output 6 Pin 6

Output GND Pins 7, 8, 9

Scaling of Measured Parameters

Analog outputs selected as voltages (‘V’ or ‘n’) provide a linear

measurement range centered around the nominal value of the

line-to-line (V

respectively. This diagram depicts the scaling of line-to-line voltage.
