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。

CPU模板的供电接线端子

Power supply terminals 供电接线端子	L+ and M terminals L+和M端子
Voltage 电压	24V DC
Current consumption 电流消耗	1A
Power consumption 功耗	24 W (entire station without field devices) 24W(整个站没有现场设备)

Make sure that the power supply unit used is rated for the required inrush current 确保所使用的电源单元额定电流满足所需的励磁电流
