ABB DSSR122模块是一款在工业自动化控制系统中广泛应用的电源供应单元。该模块具有以下主要特点和参数：

输入电压：通常为24V DC。

输出电压：5V DC。

额定电流：40 A。

工作温度范围：-20°C 至 +60°C 或 -20℃ 至+70℃。

防护等级：IP65或IP20。

尺寸与重量：不同来源提供的数据略有差异，例如，一种规格是深度238.5 mm、高度72 mm、宽度162 mm，重量为2.35 kg；另一种规格是长度238.5 mm、宽度200 mm、高度100 mm，重量为2.43 kg。

安装方式：壁挂式或DIN导轨安装。

处理器：采用16位ARM处理器，具备高性能和低功耗的特点。

内存：拥有256 KB的RAM和16 MB的Flash存储器。

通信接口：支持多种通信接口，如以太网（10/100 Mbps）。

此外，DSSR122模块还具备多种保护功能，包括过压保护、过流保护和短路保护，确保设备在恶劣环境条件下能够稳定、可靠地运行。

需要注意的是，虽然部分证据提到DSSR122模块具有以太网功能，但具体到以太网控制器模块的信息较少。例如，有证据表明某些ABB控制器模块内置了冗余以太网通信端口，但这并不直接指向DSSR122模块本身。

The ABB DSSR122 module is a power supply unit widely used in industrial automation control systems. This module has the following main features and parameters:

Input voltage: typically 24V DC.

Output voltage: 5V DC.

Rated current: 40 A.

Working temperature range: -20 ° C to+60 ° C or -20 ° C to+70 ° C.

Protection level: IP65 or IP20.

Size and weight: The data provided by different sources may vary slightly. For example, one specification has a depth of 238.5 mm, a height of 72 mm, a width of 162 mm, and a weight of 2.35 kg; Another specification is a length of 238.5 mm, a width of 200 mm, a height of 100 mm, and a weight of 2.43 kg.

Installation method: Wall mounted or DIN rail installation.

Processor: Adopting a 16 bit ARM processor, it has the characteristics of high performance and low power consumption.

Memory: It has 256 KB of RAM and 16 MB of Flash memory.

Communication interface: Supports multiple communication interfaces, such as Ethernet (10/100 Mbps).

In addition, the DSSR122 module also has multiple protection functions, including overvoltage protection, overcurrent protection, and short-circuit protection, ensuring that the equipment can operate stably and reliably under harsh environmental conditions.

It should be noted that although some evidence suggests that the DSSR122 module has Ethernet functionality, there is limited information specifically related to the Ethernet controller module. For example, there is evidence to suggest that some ABB controller modules have built-in redundant Ethernet communication ports, but this does not directly point to the DSSR122 module itself.
