Each channel consists of an optically coupled pair with a gallium arsenide infrared LED and a silicon NPN phototransistor. Signal information, including a DC level, can be transmitted by the device while maintaining a high degree of electrical isolation between input and output. 6 7 8 .390 (9.91) .379 (9.63) Cathode 2 7 Collector Cathode 3 6 Collector Anode 4 .045 (1.14) .150 (3.81) .030 (.76) .130 (3.30) 4° Typ.
