The Modbus between the Nanodac, and Thyristor pack, they must have an interface standard to write coils and read registers between them. I see what I believe is the Nanodac on a DIN rail mount. Nice safety backup. worked on autopilots, and all the safety things, back before they trusted a silicon switch for positive disengage of the servo motors, the switches in our cockpit panel, had 3 DPDT switches all ganged together and wired in series to ensure the +28VDC was removed from the engage clutch, one path for the elevator, and one for the aileron, the yaw damper had it's own separate system if needed. I learned you can't trust relays for anything, their failure rate is too small for aircraft safety. Preventing house fires is very important, I like seeing that.
