KH104 Intelligent Programmable Process Controller

Model:KH104

Product details:

¡¡¡¡KH104 programmable PID controller is high accuracy measuring and data collection compatible and has intelligent PID parameter self-setting 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. It can supply communication, transmission, feed and other auxiliary output functions. Adopting a jump instruction to achieve the usage of more than one program connection, the controller is used for accurate measurement and control of the specified value with time change. The modern universal MODBUS communication protocol is available, with maximum baud rate 19200 bit/s.
