ALSTOM MVAJ21L1GB0771B远程控制卡件现货

ALSTOM MVAJ21L1GB0771B远程控制卡件现货电源外置，排除90%故障
防止空气温度变化、湿度变化的影响下，空气、尘埃、紫外线等因素对设备的破坏。容易发生故障的地方一般在电源系统和通讯网络系统，电源在持续工作、散热中，电压和电流的波动冲击是不可避免的。通讯及网络受外部干扰的可能性大，外部环境是造成通讯外部设备故障的大因素之一。目前市场上PLC基本上是电源内置，而我们的产品采用电源外置，排除90%的故障。
继电器用的是好品牌之一—欧姆龙
商家对PLC的成本控制，选型都取决于I/O，I/O模块是PLC的重要部分。PLC大的薄弱环节在I/O端口。PLC的技术优势在于其I/O端口，在主机系统的技术水平相差无机的情况下，I/O模块是体现PLC性能的关键部件，因此它也是PLC损坏中的突出环节。顾美使用的继电器是世界十大品牌之一的欧姆龙。
通讯口特殊保护
RS-232接口数据传输速率低，传输距离有限，抗干扰能力差，RS-422采用全双工的通信方式，采用差分传输方式，抗共模干扰能力增强。顾美用的是485口，485口比232口耐压高，不容易烧坏。External power supply, troubleshooting 90%
Prevent air, dust, ultraviolet ray and other factors from damaging the equipment under the influence of air temperature change and humidity change. The most likely place for failure is the power supply system and communication network system. During the continuous operation and heat dissipation of the power supply, the impact of voltage and current fluctuations is inevitable. Communication and network are likely to be subject to external interference, and the external environment is one of the biggest factors causing communication external equipment failure. At present, PLC in the market is basically built-in power supply, while our products use external power supply to eliminate 90% of failures.
The relay is one of the best brands Omron
The cost control and type selection of PLC by the merchants depend on I/O, and I/O module is an important part of PLC. The biggest weakness of PLC is the I/O port. The technical advantage of PLC lies in its I/O port. When the technical level of the host system is different, the I/O module is the key component to reflect the performance of PLC, so it is also a prominent link in PLC damage. The relay used by Gumei is Omron, one of the top ten brands in the world.
Special protection for communication port
RS-232 interface has low data transmission rate, limited transmission distance, and poor anti-interference ability. RS-422 adopts full duplex communication mode and differential transmission mode, so its anti common mode interference ability is enhanced. Gu Mei uses 485 ports, which have higher withstand voltage than 232 ports and are not easy to burn out.
