Ladies and gentlemen, I have a question regarding the outputs on the TB6 of the Mesa 7i76e, the documentation says you can switch more than 60mA. Is that correct?
FIELD POWER 5VDC 32VDC FIELD OUTPUT CURRENT ---- 350 mA Per output (RESISTIVE LOADS AND INDUCTIVE LOADS WITH FLYBACK DIODE)
FIELD OUTPUT CURRENT ---- 60 mA Per outputĀ

Yes, as long as you have a flyback diode, loads up to 350 mA are OK

Yes, for resistive loads, up to 350mA are ok.

For an inductive load (such as the coil on a solenoid) the limit is only 60mA without a flyback diode, or 350mA with a flyback diode.

So if you want to control your 200mA relay coil you must add a flyback diode.
