タイトルまたは説明

KH**3 intelligent PID process controller has high accuracy measuring and data acquisition compatible and has intelligent PID parameter self-turning function. The controller can measure accurately and control physical parameters such as temperature, pressure, liquid level, gravity, instantaneous flow and etc. It is with manual and automatic switching function. The controller adopts omnipotent with kinds of signals. It also adopts modern advanced modular structure output functions such as relay alarm, communication, transmission and feed etc, can be configured flexibly. The alarm output function can be also configured flexibly as high limit, low limit, higher limit, lower limit. Modern universal MODBUS communication protocol is available, with maximum baud rate ****0 bit/s.
