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:
Figure 23. Voltage versus percent RLA
Notes: 0% RLA = 2 vdc
120% RLA = 10 vdc
Example: If RLA is 500 amps then
10 vdc = 600 amps.
