1756-OB32罗克韦尔 Allen-Bradley 模块

详细介绍

◆集成的PID控制器可自动调整输出频率，调节过程变量

◆三个可编程的跳变频率段防止了变频器在共振频率中连续运行，避免机械损坏

◆可选的风扇/泵类曲线针对离心风扇和泵类负载提供降电压模式

◆ 的休眠作用在系统需求降低到预先设定标准时，自动关闭机器；当系统需求增加时，自动起动机器

◆针对某些无人看管运行环境，系统断电而后恢复时，变频器将自动重起运行

◆Freeze/Fire和Purge等特定输入，可直接连接到消防等紧急安全系统

◆集成到变频器中的RS485通讯

◆内置的Modbus RTU和Johnson Metasys N2协议为可选参数，不需要额外的软件和硬件支持驱动串行接口(DSI)通讯模块和附件

◆使用DriveExplorer和DriveTools可方便地用于编程、监视和控制变频器

◆成套变频器满足UL标准，增强了安装的灵活性，允许变频器直接安装在开关柜中

◆成套变频器断路器和接触器旁路设备只需简单的装配就可以通过组合操作员面板、控制器、通讯和预先装配的功率选件进行起动

◆成套变频器旁路接触器提供三对接触器接点，当变频器处于旁路模式时，可以测试变频器的作用和隔离变频器

Detailed introduction

◆ The integrated PID controller can automatically adjust the output frequency and adjust the process variables

◆ Three programmable jump frequency segments prevent the frequency converter from running continuously in the resonance frequency to avoid mechanical damage

◆ Optional fan/pump curves provide voltage drop mode for centrifugal fan and pump loads

◆ The hibernation function automatically shuts down the machine when the system demand is reduced to the pre-set standard; Automatically start the machine when the system demand increases

◆ For some unattended operating environments, the inverter will automatically restart operation when the system is powered off and then restored

◆ Specific inputs such as Freeze/Fire and Purge can be directly connected to emergency safety systems such as fire

◆ RS485 communication integrated into the inverter

The built-in Modbus RTU and Johnson Metasys N2 protocols are optional, and no additional software and hardware support is required to drive Serial Interface (DSI) communication modules and accessories

◆ With DriveExplorer and DriveTools, you can easily program, monitor and control the frequency converter

◆ Complete sets of inverter meet UL standards, enhance the flexibility of installation, allowing the inverter to be installed directly in the switch cabinet

◆ Complete inverter circuit breaker and contactor bypass equipment can be started with simple assembly by combining operator panel, controller, communication and pre-assembled power options

◆ Complete inverter bypass contactor provides three pairs of contactor contacts. When the inverter is in bypass mode, the function of the inverter can be tested and the inverter can be isolated
