Product Features (BEDOOK RPC100-A Double Loop Web Guiding Controller )

Engineered for versatility, the RPC100-A Double Loop Web Guiding Controller stands out for its dual-loop architecture, which combines traditional sensor feedback with real-time data from vision systems. This unique design allows it to correct both lateral deviations and material stretching simultaneously, a capability rare in single-loop competitors.

BEDOOK’s commitment to innovation is further reflected in its 4.3″ TFT touchscreen HMI and modular drive outputs, enabling seamless integration with stepper motors or servo actuators in diverse industrial environments.

• Dual-Loop Control for Complex Applications: The RPC100-A’s dual-loop system merges CAN2.0 sensor data (e.g., from WS-UT ultrasonic sensors) with Ethernet-based image recognition feedback, providing dual-layer deviation correction. For example, in flexible electronics manufacturing, it can use edge sensors for primary alignment and vision systems to detect pattern registration, ensuring micron-level precision—an advantage over single-loop controllers that lack vision integration.
• Multi-Protocol Communication: With support for CAN 2.0 and Ethernet, the controller enables real-time data exchange with both industrial sensors and advanced vision systems. This flexibility eliminates the need for protocol converters, a common pain point in multi-vendor setups. Competitors often require separate modules for different protocols, increasing complexity and costs.
• Stepper Motor Integration: The built-in 2-channel stepper motor drive signals simplify actuator control, reducing the need for external drivers. This integrated design saves space in control panels and minimizes wiring errors, contrasting with controllers that require standalone motor drivers.
• Enhanced Safety with Isolation: Four channels of 24V bidirectional optocoupler isolation protect the controller from voltage spikes and EMI, ensuring stable operation in noisy environments like metal processing or automotive assembly lines. Unlike non-isolated controllers, the RPC100-A maintains signal integrity even near high-power machinery.
• Intuitive Dual-Loop HMI: The 4.3″ TFT touchscreen allows operators to monitor dual-loop parameters (e.g., primary deviation vs. secondary stretch) in real time, with customizable dashboards for quick diagnostics. This level of visibility is unmatched in basic single-loop controllers, where users must toggle between menus to access separate control parameters.
• Future-Proof Ethernet Integration: The Ethernet interface supports advanced features like OPC UA or MQTT for Industry 4.0 compatibility, enabling remote monitoring and predictive maintenance. Competitors’ controllers without native Ethernet often require retrofitting, limiting scalability for smart factory initiatives.
