A
Configure the 857-RAD Analog Outputs
From the External Analog Outputs set up screen in SetPointPS, you can scale
each of the four Analog Outputs independently. Below are shown several
variations for the configuration of the Analog Output (mA) scaling. The output
scaling is fully scalable.
Figure 12 - External Analog Outputs
Example #1 – mA Output Scaling for IL
• AO Link measurand = IL
• Minimum Analog Output value = 0 mA
• Maximum Analog Output value = 20 mA
• Linked minimum value = 0 A
• Linked maximum value= 300 A
• Modbus minimum value = 0
(Minimum Analog Output value x 1000)
• Modbus maximum value= 20000
(Maximum Analog Output value x 1000)

A
Scaled analog output minimums & maximums. These determine the output range in mA.
B
Linked Analog Output measurand. This defines which measurand is selected for the scaled value.
C
Linked minimum and maximum value. These determine the range of the linked measurand.
D
Modbus minimum and maximum value. The Modbus scaling for the analog output (factored by 1000).
