1. CANopen bus coupler (BL 210/B)
1-channel CANopen: The speed is set by a rotary switch (125k~1Mbit/s);
Power supply: Front end 24V input, maximum output power 45W@24V and 8.5W@5V ;
Protection: Full protection against reverse connection, overload, short circuit, and feedback.
2. EtherCAT slave coupler (BL 27x/x)
100Mbit/s EtherCAT: 2-channel RJ45, supporting ring network topology;
On board I/O: BL 27x/A with 4 digital inputs (interrupt capability of 100 μ s); BL 27x/B with 4 digital outputs (0.5A);
Bus via Bus: BL 272/x supports inserting communication modules such as FM 200/A and SM 210/A into remote I/O stations, achieving a complex topology of "bus backplane hanging bus slave stations".
Common Technology: Electronic Parameter Chip and Comprehensive Diagnosis
The Electronic Parameter Chip that runs through the entire series of modules is the intelligent symbol of KeConnect I/O
Plug and play: After the module is inserted, the CPU automatically reads the model, serial number, hardware version, and calibration data from the chip;
No jumper configuration: No hardware jumper is required, all filtering, debounce, interrupt enable and other parameters are issued by software;
Preventive maintenance: The chip records the cumulative power on time and switch frequency, and supports predictive maintenance.
Diagnostic ability stratification:
Channel level: digital output short circuit, overload; Analog input disconnection; Encoder disconnection;
Module level: power supply undervoltage, bus communication error;
System level: Implement collective diagnostic information transmission from remote I/O stations through bus couplers.
Environmental adaptability: Industrial grade rigorous certification
Working temperature:+5 ° C~+55 ° C (some modules can be extended to 0 ° C~+60 ° C);
Storage temperature: -40 ° C~+70 ° C;
Relative humidity: 10%~95%, no condensation;
Vibration and impact: fully comply with EN 61131-2 standard;
Protection level: IP20 (installed inside the control cabinet);
Safety certification: CE, UL 508, IEC 61131-2.
Application scenarios and selection suggestions
1. Plastic machinery (injection molding machine, blow molding machine)
First choice: IM 270/W single module covers all I/O requirements of the machine, and is matched with EtherCAT to achieve micrometer level voltage conversion accuracy;
Auxiliary: TM 240/A extended multi-channel material barrel temperature control; MM 240/A monitors the position of the ejector pin/adjustment motor.
2. Metal forming (die-casting machines, stamping machines)
DO 272/A drives high current hydraulic valve, with fast shut-off function to reduce impact;
FM 265/A is connected to the Profibus DP factory network to collect energy consumption and production data.
3. Material handling and packaging
Build a distributed picking station with BL 27x/A and DI 260/A to interrupt input and capture grabbing signals;
SM 230/A connects barcode scanners to achieve product traceability.
4. Renovation of old equipment
BL 210/B interfaces with existing third-party controllers through CANopen, retaining the original I/O module investment.
