1, the use of ultra high speed dual 16-bit CPU system work and powerful:
This product is all the measuring and protection unit adopts 80C196 chip of Intel company, its speed is 8096 twice times, the chip itself contains all the circuits. Hardware design and simplified, will protection, and control, and measurement, and communications, function reasonable of dispersed to two a CPU chip for processing, to guarantee in which a CPU occurred fault Shi can automatically switch task, great to improve has system of processing capacity, makes system run more reliable, and more security, and left has more of redundant volume, conducive to user of upgrade and extended, effective prevent system full load work.
2, COMS optimization of industrial-grade chips, whole screen requires very little power:
This product all integrated circuits using industrial-grade COMS chip, greatly reduces power consumption and system noise margins greatly improve anti-interference ability.
3, high-reliability design, rugged, comply with IEC international standards:
Specializes in the design of this product applied to magnetic interference, reliablecomponents and connectors contact resistance, impact resistance, resistance to promote. Wide operating temperature range, insulation, compression resistance, impact, and anti-interference indexes in accordance with IEC international standards.
4, communication lines, high-speed, reliable, all devices have no effect:
This product uses the private RS-485 network communications chip, fault tolerant,high reliability, and opto-isolated, fully guaranteed online all the equipment security, each in itself also has a self test system, facilitate the maintenance of Internet failure for business, when a communication failure is detected, can be automatically isolated from the communication bus.
