AQ-300 series relays protection and communication separation on CPUs

AQ-300 series units have one CPU module with two processors on the PCB:
  1. RDSP, which is responsible for the sampling and for the protection, automation and control functions
  2. CDSP, which is responsible for the communication.
In special cases there can be extra communication modules in the devices, if further ports are needed for the process bus.
