Multiple ATD conntections to LYNX-BMS possible?

I would like to use more than one Smart Battery Protect (SBP) in my Victron system. I am using a LYNX BMS and have only one H-Signal on Pin 6 which is connected to my first SBP. How can I connect a second SBP to the ATD pin on LYNX-BMS? Is it possible to use a busbar? How can two or three SBPs work independently in this case? Will all SBPs be switched off if one gets disconnected by the BMS?

What about two additional Cyrix relays? Will this be too much for the ATD relay? And if yes, how can this issue be solved?

Cyrix relays?


I'm sure if you look through the data sheets you will find how much current is required to activate them.
