RS 232C通讯模件

  AC800M的RS 232C模件提供两RS 232C标准的RJ45插口，支持调制解调，传输速率从75-19200波特率可选。

  系统也提供独立的串口通讯卡件，支持多种电气标准：RS232C、RS422及RS485。

供电单元

  目前AC800M产品系列具有三种类型的供电单元：SD821，SD822和SD823。三者均为开关电源，将交流转换为24V直流。直流电流为2.5、5、10A，输入电压范围为交流155/230V。

  转换器的软启动功能降低了浪涌和消除了电源扰动。

  三种供电电源均可冗余或非冗余使用。

RS 232C communication module

The RS 232C module of the AC800M offers two RS 232C standard RJ45 jacks that support modulation and demodulation, with transmission rates ranging from 75 to 19200 baud.

The system also provides independent serial communication cards, supporting a variety of electrical standards: RS232C, RS422 and RS485.

Power supply unit

The current AC800M product family has three types of power supply units: SD821, SD822 and SD823. All three are switching power supplies that convert AC to 24V DC. The DC current is 2.5, 5, 10A, and the input voltage range is AC 155/230V.

The converter's soft start function reduces surges and eliminates power disturbances.

All three power supplies can be used redundantly or non-redundantly.
