Changing from TTL logic to relay output

[nicolasoto]

Hello everyone,

I would like to ask for advice. I am solving the following problem:
I am solving the connection of two devices through their GPI interface and I came across the problem that the output of one device is at the TTL logic level (i.e. 0/+5V) and the input of the second device (which I want to control with the first one) is at the level of a regular „dry“ contact, i.e. a short circuit. In short, Device A (TTL output) should control device B (CONTACT input).
