DSDX452是一款ABB生产的高性能数字化电流差动保护装置。该装置具有以下参数和规格:

产品规格

差动保护类型:零序差动保护，谐波保护，远方差动保护

通讯接口:IEC61850、MODBUS、DNP3.0自适应差分电流阈值

可编程逻辑控制应用领域

DSDX451DSDX452用于20个24 V数字输入和12个数字输出的组合单元。这些输入具有与DSDI452上的输入相同的质量。输出是完全分离的继电器触点，适用于24V-240V a.c.直流电。触点上的建议最小负载为2.5VA，但适用于24伏直流电时最小负载为100 mA。带有附加字母L的装置配有低压继电器触点。触点上的最大负载为200 mA。建议触点上的最小负载为5 mA或0.05 VA。

该装置有一个集成电压源，为传感器供电提供直流24V。电压熔断。该电源也可用于向输出端供电，然后输出端可驱动电流信号通过650的负载Q.此外，输出可以从外部供应单元供应。"然后，您可以将电流信号的负载电阻增加到1000Q。

DSDX452 is a high-performance digital current differential protection device produced by ABB. The device has the following parameters and specifications:

Product specification

Differential protection type: zero sequence differential protection, harmonic protection, remote differential protection

Communication interface :IEC61850, MODBUS, DNP3.0 adaptive differential current threshold

Programmable logic control applications

The DSDX451DSDX452 is used in a combined unit of 20 24 V digital inputs and 12 digital outputs. These inputs have the same quality as the inputs on DSDI452. The output is fully separated relay contacts for 24V-240V a.c. Direct current. The recommended minimum load on the contact is 2.5VA, but it is suitable for a minimum load of 100 mA at 24 volts DC. Devices with additional letter L are equipped with low voltage relay contacts. The maximum load on the contact is 200 mA. The recommended minimum load on the contact is 5 mA or 0.05 VA.

The unit has an integrated voltage source that provides 24V DC for the sensor power supply. The voltage is blown. The power supply can also be used to supply power to the output, which can then drive the current signal through the 650's load Q. In addition, the output can be supplied from an external supply unit. You can then increase the load resistance of the current signal to 1000Q.
