FCK-801C microcomputer measurement and control device

Technical and user manual

Product Features

High precision measurement, ensuring a full range measurement accuracy of 0.2%.

The exit mode of "start+exit" and the start mode of dual command activation, as well as comprehensive software and hardware self checks, ensure the safe and reliable operation of the device.

The device adopts a fully enclosed chassis, with strict separation of strong and weak electricity, and strong anti-interference ability. Configure 3 Ethernet ports and support IEC61850 communication protocol.

The timing method supports SNTP timing, B-code timing, and GPS pulse timing. Complete report records, capable of storing 80 event records, 80 operation records, 80 remote signaling records, and 80 alarm records. Adopting a 320 * 240 large screen LCD display, a friendly human-machine interface, and a fully Chinese Windows menu mode, the structure is clear and easy to use. The function configuration is complete and can be selected through configuration tools to meet the personalized needs of customers. Xuji's independently owned "VLD" visualization tool has high software reliability.
