Detailed Product Description
KH102Process Controller with Four Limits Alarm
KH102 is a processcontroller(four limits alarm instrument) with high-accuracy measuringcompatible with data collection. The controller can measure accurately and controlmany physical data including temperature, pressure, liquid level, gravity,instantaneous flow and etc. It has kinds of additional output functions such ascommunication,transmission and feed etc,which can be set optionally.
The controlleradopts omnipotent input with kinds of transmitting signals. Output adopts themost advanced modular structure. Output functions can be configured optionally.The alarm output function can be configured availably and can be set up to high limit, low limit,deviation high limit, deviation low. The controller adopts modern universal MODBUS communicationagreement, with maximum baud rate up to 19200 bit/s.
