Principle:
Built-in 180 degree reverse coil DJ1 and DJ2 to give drive power. This drive power to get three contacts of the realy ON or OFF at the same time. Drive signal and power supply are offered from outside.
There are total 5 input termianls. #1 is public end for main and slave coil, #2,3 is for signal response to slave contact. #4 is to DJ1 coil (controlling OFF ), #5 is to DJ2 coil (controlling ON).
When order pulse signal was given and input from #5, the relay will keep ON and it will power supply to meter.
When order pulse signal was given and imput from #4, the relay contacts will break off. So the power supply of meter will cut off by it.
The relay is with self-lock. Without receiving another order, ON can't go to OFF, OFF can't go to ON even if you give out force, shaking, etc on the relay. The pulse voltage is required to be 12VDC - 24VDC. (60-100ms) . 12v-24v is not power supply but a pulse use to drive relay.
