Breaking Capacity: .............................................For Form-C relays the following ratings are applied to meet
UL508 requirements: 1 second “ON”/10 seconds “OFF” per
output relay at maximum rating
FAST PATH:
For 2 IO_A module configuration the following ratings are applied to meet UL508
requirements: 1 second “on”/ 10 seconds “off” per output relay at max rating.

3-phase positive and negative reactive energy
measurements
Principle:..................................................................Pulsed output is energized for one second and then de-
energized for one second after the programed energy
increment.
