Main performance
Using ultra-high-speed dual systems to work in parallel , powerful function. All measurement, control and protection units of this product adopt chips introduced by Intel Corporation, which are twice as fast. The chip itself contains all peripheral circuits, and the hardware design is extremely simplified, integrating protection, control, measurement
and communication. Functions such as these are reasonably distributed to two chips for parallel processing to ensure that tasks can be automatically switched when one of them fails, which greatly improves the processing capability of the system, making the system operation more reliable and safer, and leaving more memory. The amount of redundancy is conducive to user upgrades and expansion, and effectively prevents the system from working at full load.
Industrial-grade preferred chips, the entire screen has extremely low power consumption. All integrated circuits of this product use industrial-grade chips, which greatly reduces power consumption. At the same time, the system noise tolerance is greatly improved, and the anti-interference ability is enhanced.
Reliable design, resistant to harsh environments, in line with international standards. This product is specially designed for strong magnetic interference, reliable contact between components and connectors, impact resistance, vibration resistance, wide working environment temperature range, insulation, and voltage resistance. , impact, and resistance to high-frequency interference and other indicators are in line with international standards.
Xunwang is high-speed and reliable, and all devices on the network do not affect each other. This product uses a dedicated network communication chip, which has strong fault tolerance and high reliability. It also adopts photoelectric isolation measures to fully ensure the safety of all devices on the network. Each interface itself also has a self-test system to facilitate rapid repair of faults on the public network. When a communication port fault is detected, it can be automatically isolated from the communication bus.
