Percent RLA Output

2 to 10 Vdc corresponding to 0 to

120% RLA. With a resolution of 0.146%. The Percent RLA Output connections are on the terminals 1A15 –J2-1 (+) to J2-3 (Ground). The Percent RLA Output is polarity sensitive.

The following graph illustrates the output:

Notes: 0% RLA = 2 vdc 120% RLA = 10 vdc

Example: If RLA is 500 amps then 10 vdc = 600 amps.
