  TB521-ETH:AC500 terminal base.Suitable for AC500 V2.Two slots for communication modules.Ethernet interface.Two serial interfaces RS232/RS485.

  Safe Extra Low Voltage(SELV)and Protection Extra Low Voltage(PELV)To ensure the electrical safety of AC500/AC500 eCo ultra-low voltage circuits,the 24V DC power supply,communication interfaces,I/O circuits,and all connected equipment must be powered by a power supply that meets the requirements of SELV,PELV,Class 2,limited voltage,or limited power according to applicable standards.

  Safety isolation,double or reinforced insulation,and isolation of primary and secondary circuits must be observed and implemented

  install

  -Use only safe ultra-low voltage(SELV)power converters with safe current to separate the primary and secondary circuits.

  Safe isolation means that the main circuit of the main transformer must be separated from the secondary circuit through double or reinforced insulation.Protective Ultra Low Voltage(PELV)provides protection against electric shock.
