PCLT-2A

1 Characteristics

7/18

Note: 1 According to application diagram ( Figure 1) with the use of a RI = 750 Ω resistor a reverse

diode from COM to GND (VF = 0.7 V) and an opto-coupler (RLED (0V) = 15 kΩ , VF=1.2 V).

2 Same as note 1 above, but RI= 0 .

3 When no LED diode is used, connect LED pin to the COMP ground.
