In order to compete in the low-end user market HART, 2013 against ND9000 series features simplify and reduce configuration after the formation economical N7000 series. ND9000 series intelligent microprocessor core is the use of ARMRISC, 256Kb RAM 1MB Flash ROM 100000, information storage capacity of the entire life cycle. Circuit board with double lacquer seal for protection, control and communication circuit board independent store owner. Positioning control, information processing and powerful diagnostic capabilities, multi-variable parameters in real time monitoring, built-in database can continuously and automatically stored in the line trend (bias, static friction, the valve opening load, air pressure, temperature positioner, pneumatic spool stroke, control valve average speed, average speed setpoint) holding a variety of field bus communication protocol (HART Profibus-PA) and EDDL FDT / DTM. positioning control conditions meet user control features adaptive selection variant. Device Diagnostics include self-diagnostics, online diagnostics, performance diagnostics, communication diagnostics, extended off-line test.
