Product Profile of Db500 Series Digital Indicating Controllers
CHINO LAXONS is the manufacturer and exporter of Controllers. They present DB500 Series Digital Indicating Controllers. The DB500 series is high-accuracy, high-speed compact controllers with digital displays and an indicating accuracy of 0.2% and sampling frequency of about 0.2 second, incorporating high-performance microprocessors with a front panel 48 mm width and 96 mm height. They have excellent functions including an auto-tuning PID function and overshoot suppression function using fuzzy logic. A communications interface is available.
Features
Accurate control with ease of operation
The operation keys required for setting a set value, PID constants, alarms, etc. are simply arranged for accurate control with easy operation.
Auto-tuning PID function
The optimum PID constants can be set automatically, eliminating troublesome setting operations and allowing setup in a short period of time.
Overshoot suppression with Fuzzy Logic
Overshoot which tends to occur due to sudden changes such as a change of the object to be controlled or the change of a set value in a heat treating furnace, etc. can be suppressed by fuzzy logic.
Communications interface
As a communications interface and transmission signal output is available as options, control using a host computer or combination with a recorder can be performed easily.
Zone division control
Using the communications interface, a number of these controllers can be connected to control up to 32 zones, allowing tunnel kiln control, etc. Also, combination with a KP Series Digital Program Setter enables program control of a multi-zone batch furnace.
Indicating accuracy of 0.2% and sampling cycle of about 0.2 second
Even though its front panel is small [48 x 96mm], high accuracy and high speed are achieved through use of a high-performance microprocessor and A/D converter.
