Hi Everyone,
I recently bought a system that has GPIO PCI 6503 Card installed and PA0 port is configured for an alarm unit (24 static digital IO l/ines n(on-isolated 5 V TTL/CMOS) in 8-bit ports, 2.4mA).
I am trying to use solid state relay to get an output as GREEN LED in case normal operation and RED LED in case a fault or failure reported by GPIO card but it is not working at all. I understand that GPIO card has TTL/CMOS as output and SSR relay should work with it. Am I doing something wrong.
Kindly advise.
