730475-D-ELEMENTS-F2 ALSTOM   晶闸管模块 由栅极信号控制

730475-D ELEMENTS-F2 晶闸管模块是一种电子设备，用于控制电气系统中的功率流。它旨在提供高可靠性和快速开关速度，使其适用于广泛的应用，例如电机控制、加热、照明和电源。

晶闸管模块由若干个晶闸管组成，晶闸管是一种固态半导体器件，只能在一个方向上传导电流。晶闸管并联连接以提供所需的电流和电压额定值，并由栅极信号控制。

730475-D ELEMENTS-F2必须调整RCLASS1和RCLASS2的值以匹配CLSMODE引脚设置的分类。下图显示了外部分类BOM的原理图，推荐值如表2.2所示以及组件类型。详见《AN1179: Si34071 802.3bt PD PoE接口》分类BOM及选型备用组件。第一季度第二季第三季R1分类。

当ALSTOM 730475-D ELEMENTS-F2检测到CRC错误以外的错误时，将向主机发送响应。FUNCTION CODE字节的MSbit将被设置为1（即，从设备发送的功能代码将等于从设备发送来的功能代码加128）。

ALSTOM 730475-D ELEMENTS-F2以下字节将是一个异常代码，指示发生的错误类型。ALSTOM 730475-D ELEMENTS-F2将忽略从具有CRC错误的主机接收的传输。

从机对错误（CRC错误除外）的响应为：•从机地址：1字节•功能代码：1字节（MSbit设置为1）•异常代码：1个字节•CRC：2字节469实现以下异常响应代码。01-非法功能传输的功能代码不是469支持的功能之一。02-非法数据地址主机发送的数据字段中引用的地址不是ALSTOM 730475-D ELEMENTS-F2的允许地址。03-非法数据值主机传输的数据字段中引用的值不在所选数据地址的范围内。

The 730475-D ELEMENTS-F2 thyristor module is an electronic device used to control the power flow in an electrical system. It is designed to provide high reliability and fast switching speeds, making it suitable for a wide range of applications such as motor control, heating, lighting and power supplies.

A thyristor module consists of several thyristors, which are solid-state semiconductor devices that can only conduct current in one direction. The thyristors are connected in parallel to provide the required current and voltage ratings and are controlled by the gate signal.

730475-D ELEMENTS-F2 The values of RCLASS1 and RCLASS2 must be adjusted to match the classification of the CLSMODE pin setting. The following diagram shows the schematic of the external classification BOM with recommended values as shown in Table 2.2 and component types. For details, see "AN1179: Si34071 802.3bt PD PoE Interface" classification BOM and selection of spare components. Q1 Q2 Q3 R1 category.

ALSTOM 730475-D ELEMENTS-F2 sends a response to the host when it detects an error other than a CRC error. The MSbit of the FUNCTION CODE byte will be set to 1 (that is, the function code sent from the device will be equal to the function code sent from the device plus 128).

ALSTOM 730475-D ELEMENTS-F2 The following bytes will be an exception code indicating the type of error that occurred. ALSTOM 730475-D ELEMENTS-F2 will ignore transmissions received from hosts with CRC errors.

The response of the slave to errors (except CRC errors) is: • Slave address: 1 byte • Function code: 1 byte (MSbit set to 1) • Exception code: 1 byte •CRC: 2 bytes 469 Implements the following exception response code. 01- The function code for illegal function transmission is not one of the functions supported by 469. 02- Invalid Data address The address referenced in the data field sent by the host is not the allowed address of ALSTOM 730475 -d ELEMENTS-F2. 03- Invalid Data value The value referenced in the data field transmitted by the host is not in the range of the selected data address.
