Very simple question can you use one output from a RIO01 to run 2 outputs on a RLY01H (would there be enough power from the RIO01 to drive two relay points eg 3&4 indefitnetly or will I be forced to use 2 outputs from the RIO01 to control the outputs on 3&4)
There is probably enough current available from th IRIO to drove 2 coils on RLY01H, but it is better to use 2 IRIO outputs to be safe, unless you are short of outputs
