【产品详情】

 

Allen Bradley高分辨率隔离模拟模块1771-NR具有16位输入分辨率和14位输出分辨率。该模块的RTD励磁电流为1ma(典型)。其输入过压保护为140伏交流有效值连续,而失调漂移为±25 mΩ/摄氏度,增益漂移为±50 ppm/摄氏度。该单元的校准值为1.00/649.0 Ω,输入带宽为9 Hz。它的最大更新时间为25毫秒,使其具有时间效率;本机的过量程阈值为0.9 Ω,过量程阈值为650 Ω。1771-NR是作为开放式设备提供的,当在2区环境中应用时,用于不超过污染2(如EN / IEC0664-1中定义的)的工业环境。外壳应该只能通过器具接近。


1771-NR耗散功率为5伏6瓦;操作温度在0到60摄氏度(32到140华氏度)之间波动,而存储温度在-40到85摄氏度(-40到185华氏度)之间波动。本模块工作环境相对湿度为5% ~ 95%,无凝露,背板最大电流1.2 a。在拆卸或安装I/O模块之前,请先断开1771 I/O机箱插座上的电源和模块上的线缆。未能从背板上取下电源可能会导致损坏和性能问题,甚至人身伤害。

英文介绍

 

The Allen Bradley High resolution Isolated Analog module 1771-NR has 16-bit input resolution and 14-bit output resolution. The RTD excitation current of this module is 1ma(typical). Its input overvoltage protection is 140 volts AC RMS continuous, while offset drift is ±25 mΩ/ C and gain drift is ±50 ppm/ C. The unit has a calibration value of 1.00/649.0Ω and an input bandwidth of 9 Hz. It has a maximum update time of 25 milliseconds, making it time efficient; The overrange threshold of the machine is 0.9 Ω, and the overrange threshold is 650 Ω. The 1771-NR is offered as an open device for use in industrial environments that do not exceed pollution 2(as defined in EN/IEC0664-1) when applied in zone 2 environments. The enclosure should only be accessible through the appliance.


The power dissipation of 1771-NR is 5 V 6 W; Operating temperatures fluctuate between 0 and 60 degrees Celsius (32 to 140 degrees Fahrenheit), while storage temperatures fluctuate between -40 and 85 degrees Celsius (-40 to 185 degrees Fahrenheit). The relative humidity of this module ranges from 5% to 95% without condensation. The maximum current of the backplane is 1.2 a. Before removing or installing an I/O module, disconnect the power supply from the socket in the 1771 I/O chassis and cables from the module. Failure to remove the power supply from the backplane can cause damage and performance issues, or even personal injury.
