1746-P4 SLC 500电源模块
【产品详情】
1746-P4是一款SLC 500电源模块,可为本地机箱、级联模块或远程I/O机箱提供背板供电。通过提供背板电源,连接到机箱槽位的模块变得可操作,并能够被SLC处理器识别。
该电源的输入电压要求为85至132/ 170至250V ac,频率为47至63 Hz。它还提供一个24VDC输出,可用于为外部设备供电。不建议使用此24VDC输出作为输出模块的电源。这样做将使即使对单个模块也难以执行故障排除,因为必须首先关闭系统电源,这意味着必须停止整个SLC 500控制器机架。
SLC 500产品系列的所有电源都具有一个称为保持时间的特性。保持时间是指当电源模块的输入电源低于标称水平时,处理器继续处理逻辑的能力。如果电源继续经历低电压水平,并且保持时间到期,则处理器停止处理逻辑。输入电压恢复正常后,恢复正常工作。
使用1746-P4时的特定保持时间为20 ms(满载)3000 ms(空载)。该电源被UL列为工业控制设备,并通过CSA认证的过程控制设备认证,适用于第1类,第2类,A, B, C, D组危险场所。

【英文介绍】
The 1746-P4 is an SLC 500 power module that provides midplane power for a local chassis, expansion module, or remote I/O chassis. By providing backplane power, modules connected to chassis slots become operational and can be recognized by SLC processors.
The input voltage requirements for this power supply are 85 to 132/170 to 250V ac, and the frequency is 47 to 63 Hz. It also provides a 24VDC output that can be used to power external devices. It is not recommended to use this 24VDC output as the power supply for the output module. Doing so will make it difficult to perform troubleshooting even for individual modules, as the system must first be powered off, which means the entire SLC 500 controller rack must be stopped.
All power supplies in the SLC 500 product family have a feature called hold time. Hold time refers to the ability of the processor to continue processing logic when the input power of the power module is lower than the nominal level. If the power supply continues to experience low voltage levels and the hold time expires, the processor stops processing the logic. After the input voltage is restored to normal, normal operation is resumed.
The specific holding time when using 1746-P4 is 20 ms(full load)3000 ms(no load). The power supply is listed as an industrial control device by UL and certified as A process control device by CSA for use in Class 1, Class 2, Group A, B, C, and D hazardous sites.
