Hi, am trying to turn on a relay with an open collector output with 10k ohm pull up resistor and 5v DC. I get the 5v DC, but when it's wired into the relay the voltage drops to 2v DC. The relay only works at 3v-8vdc. Does anyone know why am getting the voltage drop or how to
get the relay on. Thanks.
get the relay on. Thanks.
