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.
