I am in the process of selecting the equipment. I see in the documentation that in order to achieve the required safety level, two Safety outputs are used to drive 2 power contactors in series. In my case the motors are in the range of 45-55kW so having double contactors in series is not an option as this would increase the space requirement of the MCC. What I would wish is for the safety outputs to control small relays in series (3RH2131-1BB40) that will interrupt the control voltage that drives the power conductors. Much like the 3TK28. So to sum it up, I have an ET200sp station with the E-stops connected, a couple of ET200sp stations that drive the contactors interrupting the control voltage of various motor starters that are switched on by conventional DOs. Is this setup ok? ------------------------------------------------------------------------------------------ |
