Temperature / Process Controller Guide
Controllers are the part of any control system that add value by improving the repeatability of the process, the quality of the product and in doing so reduces production costs. When choosing a controller there are several factors that you will need to take into consideration.
Capabilities / Features
Controllers vary from very simple, low cost devices, which are dedicated for temperature control (PXR). To universal input software configurable multi-loop controllers that are capable of controlling small areas of your process (CCM).
| Basic controllers like the PXR series of controllers are suitable for use with simple "Type k" thermocouples or PT100 temperature probes. They can also provide switching of heater loads and provide alarm outputs. If cost is your main consideration and you would like a controller to be available for next day delivery from our stock, then we would recommend the PXR family of controllers as being the most suitable. |  |
 | Where you have a process that requires fast response and you would like to be able to add some digital input and output switching, in addition to standard PID, or Fuzzy logic control. We would recommend the PXG family of controllers. These provide a competitive solution to mid range applications and are available with custom front panels for OEM customers. |
| Where applications are more demanding and require the processing of up to 3 inputs to be used in the control rational the PXH family of controllers would be our recommendation. This family provides fast processing times which are suitable for the control of pressure and flow applications. |  |
We are aware that the large variety of controllers on the market and the use of terminology can make choosing the most appropriate controller a difficult task. At Coulton we are committed to finding the most cost effective, long term solution to your controller needs and would be only too pleased to understand your application before making a final controller recommendation.
Physical Size
The size of the physical size of the controller may be important to you if you are replacing an existing controller and you would like to avoid cutting or blanking holes in your existing control panel. It may also be an important consideration for OEM customers where a short format controller reduces the overall depth of the control panel which leads to lower build costs. Lastly the size of the controller may make it easier to read the display from a distance. Which ever of the above is important to you, Fuji Electric have a model to suit.
The industry tends to use DIN terminology to describe the size of the front face of panel mounted controllers. The following table provides an explanation of this terminology with dimensions shown in mm. For completeness we have also shown the Fuji Electric models that satisfy the DIN sizes.
| Size | Width x Height | Panel Cut out size (W x H) | Fuji Electric Models | Length Behind the panel (mm) |
| 1/32 DIN | 48mm x 15mm | 45mm x 22.2mm | PXR3 | 97mm |
| 1/16 DIN | 48mm x48mm | 45mm x 45mm | PXR4, PXG4 | 80mm |
| 1/8 DIN | 48mm x 96mm | 45mm x 92mm | PXR5, PXG5 | 78mm |
| 72mm x 72mm | 69mm x 69mm | PXR7 | 78mm | |
| 1/4 DIN | 96mm x 96mm | 92mm x 92mm | PXR9, PXG9, PXH9 | 78mm |
| 96mm x 192mm | 92mm x 190mm | CCM |
Physical size may also be important if you require a "behind the panel" controller that is mounted on a DIN rail. In this case Fuji Electric offer the PUM range of controllers.
Mounting
They can be panel or DIN rail mounted and we will even fit them into purpose built wall mounting enclosures.
 | Price Fuji Electric are one of the largest manufacturers of electronic controllers in the world. Our pricing is driven by ability to control the whole manufacturing process. This includes the manufacture of our own silicon chips and microprocessors, A claim that no other instrumentation manufacturer is able to make. With millions of controllers being manufactured each year, economy of scale enables us to offer quality/cost breakpoints that can only be offered from a high volume manufacturer of world leading quality and reliability. |
| Delivery In the past few years we have seen that some customers just need to get their process running quickly. They are unsure of what features they require, they just need "one" now. This is where we can really help. We hold hundreds of controllers in stock. We can configure them to suit your application and provide you with a pin for pin equivalent wiring diagram for your existing controller. The controller can be sent by overnight shipper for next day delivery or for those of you who are are really in a hurry, we can even arrange same day delivery service. |  |
Configuration
All Fuji Electric controllers can be configured using software or from the front panel. We can configure the controller for you, or support you over the phone to complete the steps of setting up the correct inputs and outputs.
