Hi everyone,
short version:
I've been struggling to find an optocoupler for my application. I think this one could work: Crydom DR06D03 but the datasheet lists the turn-on and turn-off times as "1/2 Cycle" and I don't get what it means since it's all DC on both input and output side. Crydom's support service is not answering my emails.
long version:
I'm an industrial vision engineer. I'm trying here to strobe an LED light called LFVX-200SW (40W) using the output of my vision controller.
The light is powered with 48VDC instead of 24VDC to get a brighter strobe. This is allowed by the manufacturer as long as the duty cycle is less than 7%.
As you can see, the on/off time of my opto is critical to avoid damaging the light.
I've tried using a Crydom DRA1-MPDCD3, which ticks all the boxes except it keeps getting damaged. I've replaced it twice in my machine already and the same thing happens: when the controller's output is ON, the light turns ON which is great. When the controller's output turns OFF, the optocoupler doesn't turn OFF completely and "leaks" about 10VDC on the output side, leaving the light dimly lit. The opto never shuts off entierly even after I've disconnected everything on the input side.
The wiring couldn't be more straightforward:
Anyway, any help will be greatly appreciated, either in understanding that 1/2 cycle thing or fixing my leaky opto.
Thanks!
