DS2020FECNRX010A是一款数字量控制板卡，属于汽轮机控制系统的Mark V 系列的一部分。它主要用作LST TMR再热卡，是保护核心和主跳闸电路的重要组件。它包含至少两组主跳闸继电器（PTR1和2）以及三组紧急跳闸继电器（ETR1和ETR2）等。
DS2020FECNRX010A这款板卡具有多个辅助控制输出，包括电气锁定电磁阀、油复位电磁阀、机械锁定电磁阀和油测试电磁阀等。它执行多种测试，如电气超速脱扣测试、机械脱扣活塞测试等，以确保汽轮机的安全运行。
The DS2020FECNRX010A is a digital volume control board that is part of the Mark V series of steam turbine control systems. It is mainly used as the LST TMR reheat card and is an important component of the protection core and main trip circuit. It contains at least two sets of main trip relays (PTR1 and 2) and three sets of emergency trip relays (ETR1 and ETR2).
The DS2020FECNRX010A board has several auxiliary control outputs, including electrical locking solenoid valves, oil reset solenoid valves, mechanical locking solenoid valves and oil test solenoid valves. It performs a variety of tests, such as electrical overspeed trip testing, mechanical trip piston testing, etc., to ensure the safe operation of the turbine.
