Percent RLA Output
UCP2 provides a 2-10 VDC analog output to indicate % RLA. The transfer function shall be 2 to
10 VDC corresponding to 0 to 120% RLA with a resolution of 0.146%
The following graph illustrates the output:
The % RLA output is found on the Options module terminals J7-3 and J7-4. The % RLA output is
polarity sensitive.
J7-3 is +
J7-4 is -
The % RLA output’s maximum source capability is 30mA.
