KH300A mini color paperless recorder (96x96mm, 1-8 input channels, option) is TFT true color LCD display. The recorder has complete isolated omnipotent input functions, all channels are universal input such as thermocouple, thermal resistance, current and voltage, digit IO input. It can be arbitrarily set to 8 channels at the maximum. It adopts modular structure output functions such as alarm (max 2 channels), feed output, print and communication etc. Measuring data can be displayed in various types, such as graphic display as bar-graph, real-time trending, history trending memory and alarming state display. RS485/RS232 MODBUS communication is available. Recorder can be configuration with MCGS and other professional software’s with MODBUS communication protocol through RS485 or RS232 port. The history data can be derived directly by USB flash drive. Plug and play without any other further operation. Data analysis software can derive the Excel data format or curve format to print the data directly.
