In the era of automation and robotization of industry, there is a growing demand for reliable, wireless transmission of signals and data in environments where moving elements of machines and robots pose challenges to traditional cabling. The answer to these needs is a solution usingoptical technology - clutch IPC44IO-CANoffered by WObit.
Key advantages of optical technology
IPC44IO-CAN clutch usesIR transmission (infrared)for wireless transmission of both digital input/output states and CANopen protocol data over a distance ofup to 75 cm. This eliminates physical cable connections, which may be susceptible to damage or interference in moving applications.
The most important features of the device include:
- Optical transmission without electromagnetic interference - IR light is not susceptible to EM field interference, which guarantees signal stability in difficult industrial conditions.
- Range flexibility - short and long distance mode allows you to adapt to a specific application.
- Fast response and security - transmission delays below 20 ms and automatic deactivation of outputs when communication is lost improve process security.
- IP65 resistant design - the housing protects the device from dust and water, which increases its durability in an industrial environment.
- Simple installation and integration - no need to pair devices and a standard CANopen interface facilitate implementation and configuration.
Advantages over induction solutions
Induction clutches are a popular technology for contactless transmission of energy and signals through an air gap in automation. They are valued, among others: for no mechanical wear, higher system availability and vibration resistance.
However, IPC44IO-CAN optical coupling offers several practical advantagesthat may speak in its favor in specific applications:
- Immunity to electromagnetic interference: Light transmission is not subject to interference from magnetic or electric fields, which can be critical when working near large motors, inverters or other EMI sources.
- High quality digital signal: The use of the CANopen protocol over an optical link ensures stable data transfer, undisturbed by changing magnetic field conditions, which may affect the integrity of communication.
- Compact range with configuration of operating modes: Two range modes enable optimization of communication where precise positioning of elements is possible and necessary.
- Fast response and deterministic communication: Low latencies are especially important in real-time control systems where response time is critical.
Summary
Optical coupling IPC44IO-CAN is a modern solution for wireless communication in automation, especially where signal stability, immunity to electromagnetic interference and deterministic data transmission are a priority. This makes it an attractive alternative to classic contact transmission, and in some applications - also superior to induction solutions in terms of communication quality and reliability.
