NOR CONTROL NN-801-802.1-802.2

NOR CONTROL NN-801-802.1-802.2 is a classic mixed i/o interface pcb set for legacy NORCONTROL marine machinery monitoring and alarm systems. The mixed i/o interface pcb set consists of NN-801 digital adaptor board, NN-802.1 analog input board and NN-802.2 analog output board. This mixed i/o interface pcb set collects both contact signals and analog process data from engine room field transmitters. The mixed i/o interface pcb set adopts heavy-duty PCB layout to resist engine room vibration and electromagnetic interference.

This module set carries out hybrid marine signal acquisition for pressure, temperature, level and switch contact monitoring. The hybrid marine signal acquisition gathers digital contact alarm signals and 4-20mA analog field signals simultaneously. The hybrid marine signal acquisition converts raw sensor data and transmits processed information to Norcontrol main CPU. The hybrid marine signal acquisition triggers audible and visual alarms once machinery parameters exceed preset limits.

This NORCONTROL spare set is an essential legacy marine automation spare for old vessel control cabinet overhaul. The legacy marine automation spare allows individual board replacement without replacing the whole automation rack. The legacy marine automation spare meets marine classification society certification requirements. The legacy marine automation spare is widely used on older cargo ships, tankers with classic Norcontrol monitoring platform.

NOR CONTROL NN-801-802.1-802.2 mixed I/O PCB set is a full signal interface suite for classic Norcontrol marine automation system. It integrates digital adaptor, analog input and analog output functions, exchanges multi-type field signals with main controller, monitors engine room auxiliary equipment and alarm logic, runs stably under high humidity and salt mist onboard marine machinery spaces.
