Good day ppl,
I'm trying to find a SSR to plug into a RS-232 that provides 12Vdc.
From what I could find on RS-232 drivers, the cheap ones with ICs have a max of 10mA.
I was looking at the SSL1D101JD, but I'd really like if someone in the know could confirm that at 12Vdc it will only draw 4mA:
Long story short, it's to use with a Toshiba T1000 UPS and monitor a low-battery alarm.
They say not to use the RS-232 for remote contacts (because they sell a 3-400$ module to do that) but connecting a 12V 10mA relay works perfectly with pin 9 and 8 here:
Pin 9 (12Vdc) → A1 → A2 → Pin 8 (low batt). When the low batt occurs, pin 8 becomes linked to pin 5 (with a certain resistance though, I don't know why and if it matters... 128 Ohm between pin 8 et 5).
Anyway, the 12V 10mA relay works, but I don't want to burn anything in the long run so I'm really trying to find a solution under 10mA.
Thank you so much for your help !
