I am using a optocoupler (from amazon) between my 7i77D output and a solenoid valve for a spindle break in the sinking configuration, the output is over-temperature faulting for some reason.
using TB8 OUTPUT0. Field voltage is 24Vdc and driving the relay with the same 24 power supply.
I set up the opto relay on the bench and it only draws 2.2ma on the input in low position.
I'm kind of at a loss, the manual says the outputs can take up to 350ma.
Please advise
