Descriptions
Data Monitor & Emergency Controller (JMEC) 는 열악한 환경의 소형 설비의 제어를 위한 소형
컨트롤러이다. 원격지의 DATA Processor에서 Remote I/O Unit을 통해 입력된 정보를 RS422 serial
통신을 통해 운전 상태 감시 및 비상 조작하므로 설비 주변환경의 영향을 최소화 한다 .
JMEC는 Analog Input (4~20mA) 3 Points, Digital Input 24 Points, Digital Output 16 Points 의 입출
력을 가지며 FND Display, LCD Display 및 LED Lamp를 통해 표시하여 설비의 동작상태 파악이 용이하
다. 또한 통신을 통한 제어방식으로 Cable의 인입량이 적어 협소한 공간에서의 설치가 가능하다.
