6.10 Power consumption

功耗

The total power consumption of the controller corresponds to the sum of all individual consumption values. The following values must be taken into consideration:

控制器的全功耗等于所有个体功耗之和。下列值必须考虑在内。

  • the power consumption of the CPU module through the L+ and M terminals. After voltage conversion within the CPU module, the communication interfaces and the bus-connected I/O modules are supplied from here as well
  • CPU模板的功耗通过L+和M端子。在CPU内部进行电压转换后,通信接口和与总线相连的IO模板也从这里供电。
  • the power consumption for I/O modules (I/O circuit) at the ZP and UP terminals of the terminal blocks. The power for the consumers at the digital/analog outputs is also supplied from here
  • I/O模块(I/O电路)在终端块的ZP和UP端子的功耗。在数字/模拟输出为消费者提供的电源也从这里提供

A single power supply unit can be used for both supply voltages. The CPU module and the I/O modules should, however, be provided with separate fuse protection. As a matter of course, separate power supply units can also be used.

单一的供电单元可以提供所有的(模块)电压。CPU模板和IO模板本应,但是,提供单一的熔丝保护。理所当然的,独立的供电单元(方式)也被使用。
