 {"number":"1","name":"IN+","type":"passive","group":"Primary side","description":"Input current positive pin: one end of the 0.7 mOhm internal conductor (SBOSA24D p.4, Table 5-1; RIN p.8). Current flowing from IN+ to IN- gives a positive output change. This pin is on the primary (high-voltage) side of the isolation barrier."},
