KH104 is an programmable PID controller with high accuracymeasuring and data collection compatible and has artificial intelligent PIDparameter self-setting function The controller can measure accurately and controlphysical parameters such as temperature, pressure, liquid level, gravity, instantaneousflow and etc.With manual / automatic switching function. It can supply communication,transmission, feed and other auxiliary functions, which can be set optionally thecontroller adopts a jump instruction to achieve the usage of more than oneprogram connection, which is used for time varying measurement and control ofthe specified value. The controller adopts modern universal MODBUS communicationagreement, with maximum baud rate up to 19200 bit/s.
