SCHEMATICS, WIRING & PCBS
5.4 PRINTED CIRCUIT BOARDS
TROUGH UP-KICKER DUAL OPTO PCBS
THEORY OF OP. & SCHEMATIC
As light from the Transmitter LED1 falls on the Receiver LED1, it generates a Positive Bias Voltage (0.7v to 15.v) which is applied
to the Gate (G) of Q1 (Fet 2N5460) turning Q1 off. When Q1 is held off, no current flows through Q2's (2N3906) Base (B). With no
base current, Q2 is off and acts as an open switch, When the light is interrupted (blocked) R1 (Rec. Bd.) bleeds the gate voltage
off of Q1 allowing it to conduct, switching Q2 on, which acts as a closed switch. The LED2 (Trans/Rec) Circuit operates identical
as the LED1 Circuit.
