Allen-Bradley 1771- oz是一种继电器输出模块，是1771 PLC-5可编程逻辑控制器(PLC)产品家族的一部分。该模块设计有八(8)常开(N.O.)或形式A触点输出。模块的每个输出在交流电压138伏时具有30伏安的触点额定值，在直流电压125伏时具有20伏安的触点额定值。

1771-OZ输出模块占用机箱单槽位。与此模块兼容的机箱包括A系列或B系列1771-A1B, 1771-A2B, 1771-A3B, 1771-A3B1, 1771-A4B通用I/O机箱，以及1771-AM1或1771-AM2 I/O机箱。它可以安装到模块的任何可用插槽中，也可以安装到本地和远程I/O机架中。此外，它可以在安装的处理器和主机适配器支持的不同机架寻址格式中使用。

1771-OZ要求使用1771-WD接线臂来终止信号线。合适的电线尺寸是最大14轨距的绞合线，最大绝缘厚度为3/64。为了监控模块的运行，1771-OZ为模块的每个通道提供了单独的状态指示灯，以指示通道通电状态。

该模块需要特别考虑，特别是在I/O机架上电和断电期间，1771-OZ的输出通道可能会暂时改变操作状态，这是由于PLC-5电源的“软启动”行为。系列A和B 1771-OZ模块受此特性影响;但是，后期释放或更高的系列不受电源此动作的影响。

【英文介绍】

The Allen-Bradley 1771-OZ module is a digital output module for the Allen-Bradley PLC-5 system. The module supports eight normally open outputs. Each relay output status indicator provides control status updates. Each indicator light turns on when the corresponding relay is powered on. The 1771-OZ module can be installed in an empty slot in the 1771 I/O chassis. The module has a maximum rated voltage of 30va at 138 volts AC and 20va at 125 volts DC. The module voltage range is AC RMS 0 ~ 24v and DC RMS 0 ~ 24v. The maximum rated current is 100 mA per output. The DC output is rated at 2.4 watts per output and the AC output is rated at 2.4 Watts per output. The minimum contact load for DC output is 1 MA at 0 to 24 volts, and the minimum contact load for AC output is 1 MA at 0 to 24 volts. The maximum operation and release time is 1 ms. The maximum rebound time is 1 millisecond. The maximum switching frequency is 10 Hz. The Allen-Bradley 1771-OZ module has a maximum backplane current of 420 mA. The minimum heat dissipation rating is 6.9 BTU/hour and the maximum heat dissipation rating is 7.6 BTU/hour. The minimum power consumption is 2w and the maximum power consumption is 2.2w. The module provides 1000 volts of isolation between the open circuit contacts and 1500 volts of isolation between the coil and the contacts. The recommended wire size for use with the module is awg14 wire. The 1771-OZ module operates at temperatures from 0 to 60 degrees Celsius.

Allen-Bradley 1771-OZ is a relay output module that is part of the 1771 PLC-5 Programmable Logic Controller (PLC) product family. The module is designed with eight (8) normally open (N.O.) or form A contact outputs. Each output of the module has a contact rating of 30 volt ampere at 138 volts AC and 20 volt ampere at 125 volts DC.

The 1771-OZ output module occupies a single slot in the chassis. Chassis compatible with this module include A Series or B Series 1771-A1B, 1771-A2B, 1771-A3B, 1771-A3B1, 1771-A4B universal I/O chassis, and 1771-AM1 or 1771-AM2 I/O chassis. It can be installed into any available slot in the module, as well as into local and remote I/O racks. In addition, it can be used in different rack addressing formats supported by the installed processor and host adapter.

1771-OZ requires the 1771-WD connection arm to terminate the signal line. A suitable wire size is a stranded wire of up to 14 gauge with a maximum insulation thickness of 3/64. To monitor the operation of the module, 1771-OZ provides a separate status indicator for each channel of the module to indicate the channel power status.

This module requires special consideration, especially during I/O rack power-on and power-off, when the 1771-OZ output channel may temporarily change the operating state due to the "soft start" behavior of the PLC-5 power supply. Series A and B 1771-OZ modules are affected by this feature; However, late release or higher series are not affected by this action of the power supply.
