LN09C High Reliability ETS

   

Overview:

_

LN09C high reliability ETS module is an important part of LN3000 DCS distributed control system, which can complete the switch control function of all electric valves in the process of emergency trip control of plant, including the data collection, processing, calculation and real-time output of switch quantity, and transmit the relevant data to the central control operation room through communication. LN09C adopts triple redundant control concept to improve the reliability of the system.

Specifications:

    • It can realize seamless connection with DEH and DCS. LN-ETS high reliability ETS system is part of DCS and can be seamlessly connected with DCS. The points inside can be monitored in real time in DCS, and historical trends can be made for easy search.
    • High reliability and fast response speed. The response time is less than 10ns.
    • With switching protection function and first-out indication function.
    • 10ms input delay de-jittering can effectively prevent the occurrence of system malfunction caused by burrs or other interference spikes.
    • 2 CAN bus interfaces, 1 RS485 communication, 1 system reset interface.
    • 1 power supply alarm indication. If the core logic processing chip has a power supply failure, the ALM alarm indicator on the panel will light up.
    • Flexible combination, dual redundant and triple redundant structures can be realized, which can meet the safety protection requirements of various systems.
