Hi,
I am using AB 5069-L306ERS2 CPU. My system should achieve SIL-2. I have safety door switches connected to AB 5069-IB8S module, and I want to send a dry contact interlock signal to a high voltage power supply if any of these switches is activated. My question is how to connect the output signal from the AB 5069-OBV8S module to the power supply in order to make it SIL-2. Should I use 2 output channels and connect them to 2 different relays (relays contacts are connected in series)? Should I use regular relays or safety relays in this case, and what safety relays should I select?
Thanks.
