关于269PLUS-DO-211-120N-120VAC的常见问题

269PLUS-DO-211-120N-120VAC与269PLUS-DO-211-100N-120VAC的区别是什么?

这两个269 PLUS Multilin电机管理继电器非常相似。269PLUS-DO-211-100N-120VAC和269PLUS-DO-211-120N-120VAC的RTD材料主要不同。269PLUS-DO-211-120N-120VAC包含120n规格，这表明该RTD由120欧姆镍RTD组成。相比之下，269PLUS-DO-211-100N-120VAC具有100N选项，由100欧姆的镍RTD组成。除了这个区别之外，这两款269 PLUS Multilin数字继电器都是延长版本，并且在继电器故障安全代码、继电器触点布置、相位和接地ct(211)方面具有相同的规格。

269PLUS-DO-211-120N-120VAC 在外部创建并传输到保护系统

The 269PLUS-DO-211-120N-120VAC is a motor protection system in the GE Multilin 269 Plus motor management relay family. The purpose of the system is to act as a layer of protection to protect three-phase AC motors from damage due to temperature and electrical hazards. The operating voltage of the controller on the protection system is 120vac. The system uses a resistance thermal detector (RTD) to determine thermal conditions, while a current transformer (ct) is used to determine electrical conditions. The system uses 120 ohm nickel-based rtd.

The protection system uses the EnerVista Launchpad package to run its internal requirements, including setup and support. The software can communicate with external devices using multiple methods, including serial, Ethernet, and modems. Configuration files can also be created externally and transferred to a protection system. EnerVista also provides a toolkit that includes GE Multilin drivers and automatic event and waveform retrieval capabilities.

The back of the system panel contains the various inputs and outputs needed to take full advantage of the protection capabilities. There are 10 RTD inputs on the back of the panel, divided into 3 sections. RTD 1-3 and 4-6 inputs are typically used for stator winding protection. RTD 7-10 is commonly used to monitor ambient temperatures as well as motor and load temperatures. In addition, the back of the panel contains control power inputs and four output relays. There are also phase and ground CT inputs and contrast dials for the screen.

Frequently Asked Questions about 269PLUS-DO-211-120N-120VAC

What is the difference between 269PLUS-DO-211-120N-120VAC and 269PLUS-DO-211-100N-120VAC?

The two 269 PLUS Multilin motor management relays are very similar. The RTD materials of the 269PLUS-DO-211-100N-120VAC and 269PLUS-DO-211-120N-120VAC are mainly different. The 269PLUS-DO-211-120N-120VAC includes a 120n specification, which indicates that the RTD consists of a 120 ohm nickel RTD. In contrast, the 269PLUS-DO-211-100N-120VAC has a 100N option and consists of a 100 ohm nickel RTD. In addition to this difference, both 269 PLUS Multilin digital relays are extended versions and share the same specifications in terms of relay fail-safe codes, relay contact layout, phase and ground ct(211).
