Products

Overview

NR series, one of our recommended products have large display easy to read. PID algorithm with auto tuning and self tuning function. Universal input selected by parameter. Communication and various functions are equipped. You can choose from four sizes and two colors.

Bare board type NRB is also available.

Feature

Large display easy to read Process value(PV) display is 4 digits of red. Setting value(SV) display is 4 digit of green. Both are bright. Universal power supply. Available in AC100~240V. Free scale You may select the range by scaling function. Universal input You may select the sensor type from thermocouple, Pt100, DC current, DC volt by parameter. Easy operation. Easy operation by four key. Compact The depth of NR4 and NR7 is 76mm. Therefore the control box depth can be saved. Abundant alarm function Independent two temperature alarm and loop burnout alarm. Two face color You can choose the face color from two(black/white) as you like.
