Output current capacity compensator of optocoupler relay

The utility model discloses an output current capacity compensator of an optocoupler relay, which belongs to the technical field of electronic devices, solves the problem that the optocoupler relay has weak output load capacity for large current, and comprises an optocoupler relay, a first normally open contact, a second normally open contact, a first normally closed contact and a second normally closed contact, a group of normally open contact silicon controlled rectifiers which are mutually connected in parallel in opposite directions are connected in series between the first normally open contact and the second normally open contact; a group of normally-closed point silicon controlled rectifiers which are mutually and reversely connected in parallel are connected in series between the first normally-closed contact and the second normally-closed contact; the control electrodes of the normally open contact first silicon controlled rectifier and the normally open contact second silicon controlled rectifier ar
