>>>>>型号:8446-1019  数字调速器  可以接受磁性拾取单元

【功能描述】

伍德沃德（WOODWARD）8446-1019是一款具有多种功能和应用的设备。根据我所了解的信息，它可能是数字调速器或输入输出模块的型号。作为数字调速器，它可能用于工业控制系统中的速度调节和控制，提供精确的转速控制功能。作为输入输出模块，它可能用于连接和传输信号，实现与外部设备的通信和交互。

8446-1019还具有多种可用功能，包括热启动和冷启动的自动启动排序，温度输入选项，三速段的临界速度避免，外部警报输入，外部DI跳闸输入，跳闸指示和相关RTC警报事件的跳闸指示时间戳，双速和负载动态超速跳闸的峰值速度指示，零速检测，远程下垂频率死区等功能。此外，它还提供三种正常操作模式，包括配置、操作和校准模式。

在硬件方面，8446-1019可能包括两个冗余速度输入，可以接受磁性拾取单元、涡流探头或接近探头。它还具有模拟输入，可配置为27种功能中的任何一种。该装置还具有额外的二十个触点输入，其中一些默认用于关闭、提高速度设、复位和降低速度设，其他的可以根据需要进行配置。

此外，8446-1019可能满足特定的环境条件和电气标准，例如G3兼容模块的环境条件、交流电源的超压III类网络要求，以及设备等级和绝缘电压的规定。它还可能符合欧盟的电磁兼容性（EMC指令）和特定电压限间使用的电气设备（低压指令）的要求。

【英文介绍】

The WOODWARD 8446-1019 is a device with multiple functions and applications. According to the information I have, it could be the model of digital governor or input/output module. As a digital governor, it may be used for speed regulation and control in industrial control systems, providing precise speed control functions. As an input/output module, it may be used to connect and transmit signals, enabling communication and interaction with external devices.

The 8446-1019 also has a variety of available features including automatic start sorting for hot and cold starts, temperature input options, critical speed avoidance for three-speed segments, external alarm input, external DI trip input, trip indication and trip indication time stamp for associated RTC alarm events, peak speed indication for two-speed and load dynamic overdrive trips, zero speed detection, and more. Remote drop frequency dead zone and other functions. In addition, it offers three normal operation modes, including configuration, operation and calibration modes.

On the hardware side, the 8446-1019 May include two redundant speed inputs that can accept magnetic pickup units, eddy current probes, or proximity probes. It also has analog inputs that can be configured for any of 27 functions. The unit also has an additional twenty contact inputs, some of which are used by default to turn off, increase speed Settings, reset and decrease speed Settings, while others can be configured as needed.

In addition, the 8446-1019 May meet certain environmental conditions and electrical standards, such as environmental conditions for G3-compatible modules, overvoltage Class III networking requirements for AC power supplies, and equipment class and insulation voltage regulations. It may also comply with the requirements of the European Union's Electromagnetic Compatibility (EMC Directive) and electrical equipment used between specific voltage limits (Low Voltage Directive).
