【产品详情】

艾伦-布拉德利1771-OAD模块是一个12至120伏的交流输出模块。该模块采用过零技术，当输出电压低于规定电压时，通常在交流电压40至50伏时，它可以接通。它还大大降低了触点和其他可能对电流浪涌敏感的设备的压力。1771-OAD模块与一些艾伦-布拉德利底盘兼容，不包括1771-A1、1771-A2和1771-A4。该模块的输出范围为10至138伏交流电，频率为47至63赫兹，输出电流额定值为2安培。本模块的最小负载电流为5ma，在交流138v时，最大OFF状态漏电流为3.0 mA。本模块的最大功耗为13w，最小功耗为1.5 w。最大散热量为48.0 BTU/h，最小散热量为5.13 BTU/h。

当使用艾伦-布拉德利1771-OAD模块的设备，包括一个二极管，是在一个串联的负载，放置分流电阻(39 KOhm, 1瓦)在整个充电。这个电阻器使正确的输出操作。当输出关闭时，分流电阻可以使LED指示灯亮起。如果发生这种情况，请使用白炽灯代替LED。1771- oad模块接收机箱电源通过Allen-Bradley 1771 I/O机箱背板提供的电源。它需要295 mA的这个电源输出电流。将此要求添加到I/O机箱上所有其他模块的要求中，以防止背板机箱和/或电源机箱过载。

Allen-Bradley 1771-OAD是一种分立输出模块，工作电压类别为10-120VAC。本模块兼容选定的1771机箱，如1771- a1b至-A4B或更高版本的I/O机箱、1771- am1、-AM2机箱。该模块与PLC5可编程逻辑控制器(PLC)系统兼容。

该模块有16个离散输入通道，在交流电压范围为10至138V AC, 47 - 63Hz下工作。该模块不兼容1771- a1、1771- a2、1771- a4等1771机箱。此外，当使用2-Slot寻址时，它不能与同一组内的另一个输出模块或单个卡块传输模块一起使用。

电源要求本模块的背板电流要求为295 mA。他的背板电流信息必须沿着其他模块的背板电流要求添加。这是为了确保适当的电源尺寸。

该模块使用零件号为1771-WH的接线臂。接线臂是所有I/O模块的标准组件，因为该组件提供了方便的接线方法，并提供模块化，防止在更换模块时重新接线。

单个状态指示灯随模块提供。每个通道都有一个专用的LED灯，当模块激活时点亮。该指示灯为故障处理提供直观的工具。此外，还提供一个活动和保险丝指示灯，以显示模块的运行状态和保险丝指示灯。

该模块可安装在任何PLC5机箱和可用槽位上。

【英文介绍】

The Allen-Bradley 1771-OAD module is a 12 to 120 volt AC output module. The module uses zero crossing technology, when the output voltage is below the specified voltage, usually at the AC voltage of 40 to 50 volts, it can be switched on. It also greatly reduces the pressure on contacts and other devices that may be sensitive to electrical surges. The 1771-OAD module is compatible with some Allen-Bradley chassis, excluding the 1771-A1, 1771-A2, and 1771-A4. The module has an output range of 10 to 138 volts AC, a frequency of 47 to 63 Hz, and an output current rating of 2 amps. The minimum load current of this module is 5ma, and the maximum OFF state leakage current is 3.0 mA at 138v AC. The maximum power consumption of this module is 13w and the minimum power consumption is 1.5w. The maximum heat dissipation is 48.0 BTU/h, and the minimum heat dissipation is 5.13 BTU/h.

When using the Allen-Bradley 1771-OAD module the device includes a diode that is loaded in series, placing a shunt resistor (39 KOhm, 1 watt) throughout the charge. This resistor enables correct output operation. When the output is off, the shunt resistor can cause the LED indicator to light up. If this happens, use incandescent bulbs instead of leds. The 1771-OAD module receives the chassis power supply through the Allen-Bradley 1771 I/O chassis backplane. It requires 295 mA of output current from this power supply. Add this requirement to the requirements for all other modules on the I/O chassis to prevent overloading of the backplane chassis and/or the power supply chassis.

The Allen-Bradley 1771-OAD is a discrete output module with an operating voltage class of 10-120VAC. This module is compatible with selected 1771 chassis, such as 1771-A1B to -A4B or later I/O chassis, 1771-AM1, -AM2 chassis. The module is compatible with PLC5 Programmable Logic controller (PLC) systems.

The module has 16 discrete input channels and operates in the AC voltage range of 10 to 138V AC, 47-63 Hz. This module is not compatible with 1771 chassis such as 1771-A1, 1771-A2, and 1771-A4. Also, when 2-Slot addressing is used, it cannot be used with another output module within the same group or with a single card block transfer module.

Power Requirements The midplane current of the module must be 295 mA. His backplane current information must be added along with the backplane current requirements of the other modules. This is to ensure proper power supply size.

The module uses a connecting arm with part number 1771-WH. The boom is a standard component of all I/O modules as this component provides a convenient wiring method and provides modularity to prevent rewiring when the module is replaced.

A single status indicator is provided with the module. Each channel has a dedicated LED light that lights up when the module is activated. This indicator provides an intuitive tool for troubleshooting. In addition, an activity and fuse indicator light is provided to show the operating status of the module and the fuse indicator light.

The module can be installed in any PLC5 chassis and available slots.
