1771-OBN 数字直流输出模块

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)。

This digital DC Output Module, 1771-OBN, by Allen Bradley, is supplied as open-type equipment, not intended for an industrial environment greater than Pollution 2 when applied in a Zone 2 environment; it should only be accessible by using the appliance, as it contains components that are susceptible to damage by electrostatic discharge. Its electrostatic discharge is 4 kV on contact and 8 kV through the air.

The isolation voltage of this unit is around 1500 Volts of AC RMS; it comes with four groups of eight outputs, making a total of thirty-two (32) outputs with an output voltage range between 10 and 30 Volts of DC power; its output current rating is 0.5 A per output, its maximum backplane current is330 mA at 5 Volts of DC, and its isolation voltage has been tested for sixty seconds to withstand up to 500 Volts.

The 1771-OBN unit has a maximum “ON” state voltage drop of 1.5 Volts of DC power at 0.5 A, while its maximum leakage current during its “OFF” state is 1 mA per output. It dissipates about 13.7 Watts maximum and 1.7 Watts minimum of power, and its Thermal dissipation is 46.7 BTU per hour at maximum and 5.7 BTU per hour at its minimum.

This unit can be stored at any temperature between -40 and 185 degrees Fahrenheit (-40 to 85 degrees Celsius), and operates at temperatures between 32 and 140 degrees Fahrenheit (0 and 60 degrees Celsius). It can withstand a relative humidity of around 5 to 95%, without condensing, and has four fuses of 4.0 A, 250 Volts normal blow fuses (1 per group).
