MUC+valve hub New GEN - Coggle Diagram

- - - - need covers and small parts
  - - - need special cable for direct connection M12->valve
    - - how to connect to frequency drivers
      - washing machines
      - inkjet printer
- - - - small machines OK
      - Namur supply
      - high refresh rate
        
        mass flow meters
        
        manchester code
    - - small machines OK
      - pwm/dual level driving
      - need cable for directly connecting valves M12 to valve
      - high refresh rate
    - - power supply + network
      - Input / Namur hub
        
        cons: Ex/EMC approval
        
        Namur inputs x4
        
        cpu for analog sampling
        
        add Namur power supply

      - cons: CPU workload
      - polling speed
    - - Output / Valve hub
        
        generic outputs
        
        pro: 1 module with selectable pin usage: valve or generic ?
        
        valves
        
        cons: Ex/EMC approval
      - power supply + network
    - - difficult concept ?
        
        electronics
        
        switch the whole board functionnality, all out or all in
      - pro: single plastic mold/save on mechanics
      - cons: more electronics components cost
      - pro: one PCB only
        
        pro: one Ex/EMC approval
