Opening, opening and operating circuits

1, the external open circuit: There are eight external open circuit, are used DC220V directly into the way, the device software to take anti-shake measures to avoid the wrong letter.

2, the logic relay: logic relay directly driven by the CPU plug-in, such relays include: trip relay, closing relay.

3, the operating circuit: DC220V or AC220V for the operating power, which consists of a variety of operating circuit trip relay. Including trip position relay TWJ, closing position relay HWJ, manual trip relay STJ, trip holding relay TBJ, closing holding relay HBJ and so on. Tripping, closing the holding current adjustment using adaptive way, the range of 0.5A-4A, the use of such circuit to avoid the need to change the parameters of the trip relay need to replace the corresponding relay trouble.
