Hi,
My company uses Schmersal SRB-C.46 relays in an emergency stop circuit. The relay has 3 NO outputs and 1 NC output for monitoring. When the power is connected to the relay – will the NO contacts close and the NC open? Or is it the emergency input alone that triggers this? Cant really make sense of the NO / NC part of the drawings. The drawing shows the NO contacts as open – but when everything is running as normal these contacts will have to be closed or?
E-stop is connected to S12 – S11. When this signal changes state – K1 and K2 will also change state right?
