Kehao-On-off Temperature Controller-KH101

KH101 is an on-off process controller with high-accuracy measuring and data collection compatible. The controller can measure accurately and control many physical data such as temperature, pressure, liquid level, gravity, instantaneous flow and etc. The controller adopts omnipotent input with kinds of input signals. It also adopts modern advanced modular structure output functions such as relay alarm, communication, transmission and feed etc, can be configured flexibly. There are two- position and three –position control modes. The alarm output function can be configured optionally. Modern universal MODBUS communication protocol is available, with maximum baud rate 19200 bit/s.
