Description

The DE-CONx dosing control supports the operation of differential feeder when dosing bulk materials and powders using dosing screws, vibrating chutes, belts, etc. Thanks to the continuous performance determination and evaluation, automatic performance adjustment can be made at any time.

Highlights:
• Regulates the setpoint-precise dosing according to the “loss in weight” principle in a continuous process
• Supports the gravimetric and volumetric operation
of differential feeders when dosing bulk materials and powders
• Highly precise dosing due to adaptive control
• Optimized refill handling
• Integrated control of a conveyor system (option)
• Automatic scale adjustment
• Speed ​​monitoring of the discharge device (digital / analog)
• Continuous performance determination and evaluation for automatic performance adjustment in start-up and shut-down operation
• Single and batch operation
• Time-related throughput counter
• Control of additional components for product activation
(screws, knockers) and dust prevention (filters, suction)

Features:
• Digital filtering of the weight values ​​(digital/analog recording) for an exact calculation of the conveying capacity
• High-resolution weight value recording via digital/analog load cells
• Direct connection of load cells (4/6-wire technology)
• Serial/analog control of the frequency converter
• Internal alarm memory
• Integrated web server for complete configuration and parameterization
• Can be used as a DIN rail device in the control cabinet or directly in the system
• 4 digital inputs and outputs with a range of standard functions
(release, operating contact, external fault, refill process, alarm, etc.) can be assigned or are available for free use
