750-P5-G5-S5-HI-A20-R-T is GE Multlin’s 750 series feeder management relay. This type of management relay is one of several types in General Electric’s controlled inventory. 750-P5-G5-S5-HI-A2O-R-T provides programmable setpoint menu navigation. The keyboard can be used to browse the on-site menu. This provides direct access to metering, status, maintenance, stroke counters, arc current, and other settings. It must be noted that the setting will be used immediately after input, so caution should be exercised when inputting the setting into a relay in operation. However, the device provides hardware and password security features to lock in unauthorized changes.

PLC控制器本身的硬件采用积木式结构，各厂家产品结构大同小异。以日本欧姆龙C200HE为例，为总线模板框式结构，基本框架(CPU母板)上装有CPU模板，其它槽位装有I/O模板;如果I/O模板多时，可由CPU母板经I/O扩展电缆连接I/O扩展母板，在其上装I/O模板;另一种方法是配备远程I/O从站等。这些都说明了PLC厂家将硬件各部件均向用户开发，便于用户选用，配置成规模不等的PLC，而且这种硬件配置的开放性，为制造商、分销商(代理商)、系统集成商、最终用户带来很多方便，为营销供应链带来很大便利，这是一大成功经验。
