Hi, I am working on a Triac load control using a 4-20mA signal as an input. Have used a TCA785 and the output from Pins 14 & 15 are fed via 2 forward biased diodes and a resistor to MOC 3021. The triac works just fine and I get a decent output regulation on the input 4-20mA variation.
What should I do to my circuit to change the Triac to a antiparallel Thyristor. (I have tried what was given in the 785's datasheet, but that is not suitable for me)
Can anyone suggest minor modifications so that I can remove the triac and put in a thyristor and achieve the same results.
(My power supply is Supply: + 12V and gnd)
Thanks in advance.
