CANopen interface relay output module * CANopen module with 16 digital outputs

Product Description – Relay output module with CANopen interface

The UC-CANopen-REL16 is a high-performance relay output module designed for industrial applications where reliable switching and high operational safety are critical. Via the integrated CANopen interface compliant with CiA 301/305/401, the Relay output module with CANopen interface can be seamlessly integrated into standardized automation networks and operated both as a stand-alone device and as part of a network of multiple modules. The 16 relay outputs are rated for up to 5 A and, thanks to their normally open (NO) function, provide a robust foundation for classic switching tasks in machine and plant control systems.
Each channel has its own status LED, which significantly simplifies diagnostics during operation. The galvanic isolation of the CAN interface up to 500 V increases immunity to interference and protects the system in demanding industrial environments. WAGO’s screwless plug-in technology and the DIN-rail bus enable fast, mis-plug-proof installation and modular expandability.
Typical applications range from the safe switching of external loads in production facilities to decentralized machine control in CANopen networks, as well as inspection and test systems where reproducible switching operations and high reliability are required. Thus, the UC-CANopen-REL16 offers a durable, industrial-grade solution for modern automation projects.

Standardized CANopen communication for industrial automation networks

The CANopen interface of the UC-CANOPEN-REL16_5A is based on the internationally established CiA® specifications 301, 305, and 401 and enables reliable and standardized integration into industrial fieldbus environments. By supporting CAN 2.0A and CAN 2.0B, a high level of compatibility with a wide range of control and automation systems is ensured. Galvanic isolation of the bus connection provides robust signal transmission and reliably protects communication against interference in harsh industrial environments. Device addressing is conveniently carried out via integrated rotary coding switches, allowing the node ID to be set directly on the device at hardware level, which enables fast commissioning without additional configuration software. In addition, the baud rate can be flexibly adapted to the respective network, ensuring easy integration into existing system architectures. Furthermore, the interface on the module supports data rates of up to 1 Mbit/s as well as features such as auto-baud detection to further simplify commissioning. This results in a powerful, stable, and standards-compliant communication solution that supports both fast installation and reliable operation in industrial environments.

Flexible control via CANopen for easy system integration

The control of the UC-CANOPEN-REL16_5A is fully based on the standardized CANopen protocol, enabling seamless integration into existing automation and control systems. By supporting the object-oriented communication model according to CiA 301, all functions are addressed and controlled via the Object Dictionary. Configuration is conveniently performed using standardized communication objects such as SDOs, while cyclic process data exchange via PDOs ensures fast and deterministic response in real-time operation.
In addition, the Relay output module with CANopen interface supports typical CANopen Network Management (NMT) functions, enabling defined start, stop, and error states of the device within the network. Flexible assignment of node ID and baud rate simplifies adaptation to different network topologies and control environments. Thanks to this consistent implementation of the CANopen standard, the module can be efficiently integrated into existing automation architectures and centrally operated via the control system.

Powerful relay outputs for reliable industrial switching tasks

The UC-CANOPEN-REL16_5A provides digital outputs in the form of relay contacts designed for reliable switching of electrical loads in industrial environments. The outputs are rated for switching currents of up to 5 A, enabling the safe operation of typical industrial consumers. They also support switching voltages across common AC and DC applications up to the limits specified in the datasheet, offering flexible application possibilities.
Galvanic isolation between the control and load side ensures high operational safety and effective decoupling of sensitive electronics. Each output on the Relay output module with CANopen interface is equipped with a status LED that visually indicates the switching state directly on the device, significantly simplifying diagnostics. The relays are designed for a long service life and ensure reliable continuous operation even under frequent switching cycles.

Compact DIN rail design with modular system integration

Das Relay output module with CANopen interface ist für die Montage auf der DIN-Hutschiene ausgelegt und verfügt über ein kompaktes, industrietaugliches Gehäuse, das auf den Einsatz in rauen Automatisierungsumgebungen optimiert ist. Die elektrischen Anschlüsse sind über robuste, steckbare Klemmsysteme realisiert, die eine vibrationssichere Verdrahtung und eine schnelle Installation ermöglichen. Ein zentrales Merkmal ist der integrierte T-Bus, der als interner Systembus sowohl die Kommunikation als auch die Versorgungsspannung zwischen mehreren Modulen ohne zusätzliche Verdrahtung durchreicht. Dadurch entsteht eine durchgängige Backplane-Struktur, bei der Module mechanisch auf der Hutschiene verbunden und elektrisch automatisch gekoppelt werden. Der T-Bus reduziert den Verkabelungsaufwand erheblich und sorgt gleichzeitig für eine saubere, EMV-optimierte Systemarchitektur mit geringem Störpotenzial. Über die modulare Steckmechanik lassen sich weitere Teilnehmer einfach ergänzen, ohne das bestehende System neu verdrahten zu müssen. Die CANopen-Kommunikation des UC-CANOPEN-REL16_5A wird dabei nahtlos in diese T-Bus-Struktur eingebettet, wodurch eine skalierbare und systematisch aufgebaute Netzwerktopologie entsteht.
Zusätzlich verfügt das Relay output module with CANopen interface über integrierte Drehkodierschalter zur schnellen und einfachen Parametrierung direkt am Gerät. Über diese lassen sich zentrale Einstellungen wie beispielsweise die Node-ID ohne Softwarezugriff konfigurieren. Dies ermöglicht eine besonders schnelle Inbetriebnahme sowie eine eindeutige Geräteadressierung im Feld. Die Einstellung erfolgt dabei robust und manipulationssicher, auch im spannungslosen Zustand.

Integration and Operational Safety

The UC-CANOPEN-REL16_5A is a robust solution for industrial applications that require reliable processing of digital signals. Thanks to stable drivers, clear documentation, and the ICT diagnostic tool, the module can be quickly integrated into existing systems. The galvanically isolated electronics, “Made in Germany,” ensure high operational reliability, while regular updates and direct developer support enable long-term, stable use in professional environments.
