1771-OBN 数字直流输出模块 有32个输出

【产品详情】

这个数字直流输出模块，1771-OBN，由艾伦布拉德利，作为开式设备提供，不适用于污染大于2的工业环境，当应用于2区环境时;它只能通过使用器具来访问，因为它包含容易被静电放电损坏的组件。其接触静电放电为4kv，空气静电放电为8kv。

本装置的隔离电压约为交流有效值1500伏;它有四组8个输出，总共有32个输出，输出电压范围在10到30伏之间;其输出电流额定值为每输出0.5 A，其最大背板电流为330 mA，直流电压为5伏，其隔离电压已测试60秒，可承受高达500伏。

1771-OBN单元的最大“开”状态电压降为1.5伏，直流功率为0.5 a，而其“关”状态下的最大泄漏电流为每输出1ma。最大功耗约13.7瓦，最小功耗约1.7瓦，最大散热为46.7 BTU /小时，最小散热为5.7 BTU /小时。

该装置可以在-40至185华氏度(-40至85摄氏度)的任何温度下存储，并在32至140华氏度(0至60摄氏度)的温度下运行。它可以承受约5%至95%的相对湿度，不凝结，并有四个保险丝4.0 a, 250伏的正常熔断器(每组1个)。

【英文介绍】

This digital DC output module, 1771-OBN, provided by Alan Bradley, as an open device, is not suitable for industrial environments with pollution greater than 2, when applied to zone 2 environments; It can only be accessed by using the appliance, as it contains components that are easily damaged by electrostatic discharge. The contact electrostatic discharge is 4kv and the air electrostatic discharge is 8kv.

The isolation voltage of the device is about 1500 volts AC RMS; It has four sets of eight outputs for a total of 32 outputs in the output voltage range of 10 to 30 volts; Its output current rating is 0.5 A per output, its maximum backplane current is 330 mA, its DC voltage is 5 volts, its isolation voltage has been tested for 60 seconds and can withstand up to 500 volts.

The 1771-OBN unit has a maximum "on" state voltage drop of 1.5 volts and a DC power of 0.5 a, while its "off" state maximum leakage current is 1ma per output. The maximum power consumption is about 13.7 watts, the minimum power consumption is about 1.7 watts, the maximum heat dissipation is 46.7 BTU/hour, the minimum heat dissipation is 5.7 BTU/hour.

The device can be stored at any temperature from -40 to 185 degrees Fahrenheit (-40 to 85 degrees Celsius) and operated at temperatures from 32 to 140 degrees Fahrenheit (0 to 60 degrees Celsius). It can withstand relative humidity of about 5% to 95%, does not condense, and has four 4.0-A, 250-volt normal fuses (1 per set).
