1771-OB 直流输出驱动模块 可以控制直流电机启动器

【产品详情】

艾伦布拉德利1771-OB是一个直流输出驱动模块，可以控制直流电机启动器，指示器和螺线管。它通过1771 I/O背板机箱从电源外壳接收电力，需要从该电源输出165 mA。本设备装在防静电袋中，防止静电放电损坏。在某些情况下，静电放电可能会降低模块的性能或损坏模块。操作本模块前，请佩戴合格的接地钩装置或接触接地物体以使其脱落。

1771-OB具有8个输出，输入电压范围为10 ~ 27v DC，每个输出电流为1.5 A(每个模块不超过8a)。其最大浪涌电流为4 A，持续1毫秒，每1秒可重复一次。

该单元的关闭状态泄漏电流为每输出1 mA，而其打开状态电压降为2伏直流。

延迟时间为10毫秒，该模块的功耗为16.9瓦(最大)和0.9瓦(最小);最大散热量为57.6 BTU/h，最小散热量为3.0 BTU/h。

在非工作状态下，该模块的温度保持在-40到185华氏度(-40到85摄氏度)之间，而在工作状态下，温度保持在32到140华氏度(0到60摄氏度)之间。此外，该机组可保持相对湿度在5%至95%之间，不结露。

【英文介绍】

The Alan Bradley 1771-OB is a DC output driver module that can control DC motor starters, indicators and solenoids. It receives power from the power supply housing through the 1771 I/O backplane chassis, requiring 165 mA output from that power supply. The device is packed in an ESD bag to prevent damage by electrostatic discharge. In some cases, electrostatic discharge may degrade the performance of the module or damage the module. Before operating the module, wear a qualified grounding hook device or touch the grounding object to make it fall off.

The 1771-OB has eight outputs with input voltages ranging from 10 to 27v DC and each output current of 1.5 A(no more than 8a per module). Its maximum surge current is 4 A for 1 millisecond and can be repeated every 1 second.

The unit's off state leakage current is 1 mA per output, while its on state voltage drops to 2 volts DC.

The delay time is 10 milliseconds, and the module's power consumption is 16.9 watts (maximum) and 0.9 watts (minimum); The maximum heat dissipation is 57.6 BTU/h and the minimum heat dissipation is 3.0 BTU/h.

The module's temperature is kept between -40 and 185 degrees Fahrenheit (-40 to 85 degrees Celsius) when not in operation, and between 32 and 140 degrees Fahrenheit (0 to 60 degrees Celsius) when in operation. In addition, the unit can maintain a relative humidity between 5% and 95% without condensation.
