The rkc controller was developed by Japan and is mainly used in plastics and stoves. Of course, it is also widely used in China's industry, there are many people who don't know much about the rkc controller, and some even feel unfamiliar, let's take a look at the rkc thermostat together, find its uniqueness, taste its unique charm, and let you have a new understanding. At the same time, it also briefly introduces its wiring, installation, control methods and some precautions, so that you can easily control and deal with the things around you. Here's an introduction to all aspects, so check it out.
Uniqueness
fold
When the RKC thermostat comes out, it is a single-loop regulator, that is, there is only a heating function, which is called the basic table, which is generally sent to the agent, and the agent will expand the multi-channel adjustment and alarm output control function, which is called "changing the table" in the industry, which ensures that the multi-function expansion can be achieved with little hardware cost, which is a function that other thermostats do not have, in addition, the input range and alarm range of the RKC thermostat can be set by # software and parameters, which is more convenient, The overcurrent protection function can be realized by the impressed current transformer, with 485 communication port, which can communicate with the host computer.
Control method folding
The control method of RKC temperature control meter is divided into two modes of heating and cooling, cooling is divided into air cooling and water cooling, the single-loop heating mode is mostly used on general industrial equipment, the heating method has heating wire and steam heating, heating wire heating is relatively simple, it is realized by the heating mode of resistance, and the steam heating mode is realized by adjusting the valve of the RKC thermostat to achieve the control of steam volume.
Precautions folding
a. The instrument is installed in the following environment:
Overvoltage class II
Pollution level 2
. Avoid the following when installing:
The ambient temperature is below 0°C or above 50°C
Ambient humidity is less than 45% or greater than 85% RH
Sudden changes in ambient temperature can cause condensation
Corrosive, flammable gases
Direct vibration or impact of the main structure
Water, oil, chemical, smoke or vapor contamination
Excessive dust, salt, or metal powders
Excessive noise, static electricity, magnetic fields, or noise
Direct blowing of air conditioning
When used indoors, do not place in direct sunlight
Where heat radiation accumulates
Install the fold
(1) According to the size of the opening on the disc surface, a rectangular square hole for installing the instrument is punched on the disc surface.
(2) Embed the instrument into the opening of the panel
(3) Insert the mounting bracket into the instrument mounting slot.
(4) Push the mounting bracket to make the instrument and the panel firmly combined, and then tighten the screws with a screwdriver, but to prevent overtightening.
(5) Use screws to also set the instrument on the disk surface, insert the mounting bracket into the instrument and then use two screws to fix the instrument on the disk surface, when tightening the screws, when the screws touch the disk surface, you can tighten it again, please use the attached screws.
The wiring is folded
Take CD901 as an example,
L(1) pin to 220 volt live wire,
N(2) pin 220 volt neutral wire,
3,4 pins for the first output,
5,6 pins for the second output,
7, 8, 9 pins are alarm output,
The last three pins are connected to the thermocouple or PT100 temperature sensor signal [1]
Control method folding
The control method is divided into two modes of heating and cooling, and the cooling is divided into air cooling and water cooling, and the single-loop heating mode is mostly used on general industrial equipment, and the heating method has heating wire and steam heating, the heating wire heating is relatively simple, which is realized by the heating mode of resistance, and the steam heating mode is to realize the control of steam volume by adjusting the valve of the RKC thermostat.
