Adopting industrial grade Cortex-M3 series controllers and embedded real-time operating systems.
Excellent electromagnetic compatibility performance, able to resist interference from high voltage spikes, strong magnetic fields, strong static electricity, lightning surges, and has a strong range of environmental adaptability.
Upstream communication adopts communication methods such as GPRS/CDMA/4G, Ethernet, fiber optic, etc.
The downlink communication adopts 485 bus communication.
The wide voltage range design makes it more reliable and adaptable to the working environment.
New maintenance concept: With powerful configuration capabilities, device parameters can be easily modified locally/remotely, and online software upgrades are supported.
The large capacity motherboard FLASH storage chip ensures convenient storage of various data.
Sealed design, using insulated flame-retardant materials, wall mounted structure, lightweight volume, and easy installation.
