☆型号：1797-OB4D 非隔离源输出模块 输出通道
【产品详情】
1797-OB4D 是一款非隔离源输出模块，属于 1797 系列模拟模块。该模块由 Allen-Bradley 设计和制造。Allen-Bradley 非隔离式电源输出模块有 4 个输出通道，这些通道都以单个电源为参考，带有一个黄色 LED 指示输出电流状态，这意味着如果输出打开，LED 将被激活。这 4 个通道每 2 毫秒从背板更新一次。Allen-Bradley 1797-OB4D 非隔离源输出模块在 9 伏时的功耗为 7.5 瓦，功耗为 5 瓦。其散热能力为每小时 17.07 BTU，工作电压为 25 伏直流电。
Allen-Bradley 1797-OB4D 非隔离源输出模块具有故障指示功能，在这种情况下，状态指示灯将闪烁红色表示已检测到的任何故障。该输出模块能够使用模块数据位检测每个通道的短路和输出断线。Allen-Bradley 非隔离式源输出模块具有电子短路保护，可直接向控制器报告故障。推荐的使用条件是工作温度范围为 0 至 50 摄氏度，相对湿度范围为 5% 至 95%，无冷凝。还建议海拔1000米。1797-OB4D模块的大致尺寸如下：宽度为46毫米，高度为94毫米，深度为75毫米。

【英文介绍】
The 1797-OB4D is a non-isolated source output module belonging to the 1797 series of analog modules. The module was designed and manufactured by Allen-Bradley. The Allen-Bradley non-isolated Power output module has 4 output channels, each of which is referenced to a single power supply, with a yellow LED indicating the output current status, which means that if the output is turned on, the LED will be activated. These four channels are updated from the backplane every 2 milliseconds. The Allen-Bradley 1797-OB4D non-isolated source output module consumes 7.5 watts at 9 volts and 5 watts. It has a heat dissipation capacity of 17.07 BTU per hour and an operating voltage of 25 volts DC.
The Allen-Bradley 1797-OB4D non-isolated source output module has a fault indication function, in which case the status indicator will flash red to indicate any fault that has been detected. The output module is capable of detecting short circuits and output breaks in each channel using module data bits. The Allen-Bradley non-isolated source output module has electronic short circuit protection to report faults directly to the controller. The recommended operating conditions are an operating temperature range of 0 to 50 degrees Celsius, a relative humidity range of 5% to 95%, and no condensation. An altitude of 1000 meters is also recommended. The approximate dimensions of the 1797-OB4D module are as follows: the width is 46 mm, the height is 94 mm and the depth is 75 mm.
