JC series programmable multi-loop controller

 

JC series controller is a kind of multi-loop controller with high accuracy, high efficiency, multi-function and multi-applications. It comprises temperature, carbon potential, and oxygen content. They are applied in the independent control or network control of the process single loop, double loops, and three loops.

  • 15 bits A/D conversing, 0.1 degree accuracy.

  • Double 4-bit high brightness LED display, 8-key operation.

  • 3way analog input, the special port for oxygen sensor.

  • 4-way switch output, 2-way analog output (or 2-way auxiliary switch output).

  • With RS485 or RS232C communication port, network control can be used.

  • Value setting/programming, manual/automatic, run/stop, connect/hold exchange without interrupt.

  • Configuration for output, flexible, with ON-OFF, position proportion, time proportion, pulse and many ways, suitable for different environment requirement.

  • Free input, thermocouple, current, voltage, and other signals can be input.

Many meters derive from the JC series intellectual programmable multi-loop controller, mainly temperature series; carbon potential, temperature control, meter series  and oxygen content .

 

  • JCT-1 single loop atmosphere carbon potential controller. It is applied in the atmosphere carbon potential control for single zone; it has the function of electrical drive valve, potential valve, solenoid valve. It can put enriching gas, carrier gas, diluting gas under control. It has the functions of oxygen sensor auto-maintenance, alarm of many kinds, carbon monoxide compensation calculation of carbon potential, and etc.
  • JCT-2 network loop controller. It formed a regional network with 1-4 temperature controllers, applied in controlling the equipment with sing or multi temperature zones. For example: pit furnace, batch furnace.
  • JCT-3 double-loop controller. Performing the control of temperature and atmosphere. Besides the function of single-loop atmosphere carbon potential controller, it added a loop of temperature closed-ring control, applied in pit furnace, batch furnace, and so on.
  • JCT-4 three loop controllers, accomplishing close-loop control and process management of 2-zone temperature and 1-zone atmosphere, specially designed for standard pit gas carburization furnace, and so forth. It is simple and economical, especially suitable for medium and small sized enterprises.
