I. Product Overview
Brand: Coperion K-Tron (KaiChuang under Coperion)
Product Series: SmartConnex Feeding Control System
Equipment Type: Integrated weighing control for single feeding unit + motor drive module
Positioning: Each loss-in-weight/volumetric feeding unit comes with a controller as standard, directly installed on the feeding machine body, responsible for high-precision continuous batching and flow closed-loop control of powder and granular materials.
Core Control Mode
Loss-in-Weight: Main mode, short-term feeding accuracy can reach ±0.25%, used in high-precision batching scenarios
Volumetric: Switched for material storage replenishment stage, relying on screw rotation to stabilize feeding
Supports screw, vibration, belt, liquid feeding unit drive control, compatible with SFT II/III full series weighing sensors
Hardware Electrical Parameters
Power Supply: 115/230V AC 50/60Hz, maximum drive power 2000W
Protection Grade: IP65 (wall-mounted / installed on the machine body, dust-proof and splash-proof water-proof)
Operating Temperature: -10℃ ~ +60℃; humidity 5%~95% RH without condensation
I/O Configuration: 8 digital input/output, 4 analog input
Drive Type: Built-in DC servo drive, supports DC motors, stepper motors, vibration drive
Installation Method: Wall-mounted, directly fixed installation on the feeding machine body
Safety Certification: CE, ATEX 3D, NEC II Class 2 Zone explosion-proof certification, suitable for dust explosion-proof working conditions
Communication Interfaces and Bus Protocols
Local Interfaces: RS232 (computer debugging, SmartConfig parameter download), dual RS485 (K-NET bus)
Industrial Fieldbus (optional communication card)
Modbus RTU/TCP, Profibus DP, DeviceNet, EtherNet/IP
Network Configuration
K-NET bus can connect KSU-II single operation panel, K-Vision multi-unit upper controller, up to 30 feeding units can be networked for centralized monitoring
Can directly connect to Siemens, AB, etc. PLC/DCS upper systems for remote setting, flow collection, start-stop control
Core Function and Features
Integrated Integration Design: CPU control board + servo drive board + button display screen in one, eliminates the need for external drive, simplifies on-site wiring
Multiple Formula Storage: Can preset multiple sets of material process parameters, change materials with one-click call, suitable for multi-product flexible production
Closed-loop PID Flow Regulation: Patent screw rotational speed pulsation compensation algorithm, short-term feeding accuracy improves by 50% in low-speed conditions
Full Dimension Fault Self-Diagnosis: Weighing sensor breakage, motor overload, low material level, communication abnormality, out-of-tolerance alarm, local code + remote alarm on the upper level
Production Data Recording: cumulative feeding quantity, real-time flow, running time storage, used for process traceability, OEE equipment efficiency statistics
Support for vacuum feeding machines, stirring motor linkage control, achieving full-process interlock of batching and transportation
Typical Application Industries
Plastic extrusion, modification granulation, color mother batching
Fine chemicals, coatings, lithium battery powder batching
Food, medicine, feed high-precision continuous mixing batching
Plastic, building materials powder automatic ratio production line
Iteration Differences of the Same Series Models
KCM-2: Classic old model, button LCD screen, RS485 as the main interface, Ethernet requires selection of communication card, the most industrial inventory is the largest KCM-3 (KCM-III): Upgraded model, 5-inch color touchscreen, built-in network port, supports WiFi, integrates web-based remote debugging and predictive maintenance functions
