  • Can you give an advise, please: I’ll use TLC5940 with mbed to drive 16x SSR relays. Can I connect SSR directly to my TLC5940' PWM-out? As I understand, just using mbed’s TLC5940-library I can limit a current by 20mA, and set voltage to 1,2V as shown in SSR’s DataSheet (S202S02F). Should I use driver circuit (with a transistor, a current limiting resistor, …), or I can straightly connect PWM-out to the + of the SSR?

    Thanks in advance!
