CANopen A/D voltage reading * CANopen module with 16 analog inputs

Product Description – CANopen A/D module for reading voltage signals

The CANopen A/D module UC-CANOPEN-AD16-16/18 is a high-precision A/D acquisition module designed for industrial measurement and automation tasks. With 16 analog inputs and a choice of 16- or 18-bit resolution, the device enables extremely precise digitization of voltage and current signals. Voltage ranges from ±5 V to ±40 V and current ranges of 0–24 mA available—ideal for sensors, transducers, and process signals. Electrical isolation up to 500 V reliably protects connected systems and the module from interference and potential differences.

The electrical isolation of the inputs and the CAN bus ensures safe and interference-free signal processing, even in industrial environments with high EMC loads.
The module supports the CANopen profiles CiA 301, CiA 305, and CiA 401, allowing it to integrate seamlessly into existing CANopen networks. Node number and baud rate can be conveniently configured via DIP switches or LSS.

Typical applications include reading sensor voltages, monitoring analog measured variables such as temperature, pressure, or level, as well as use in test benches and industrial automation systems where reliable CANopen AD signal processing is required.

Standardized CANopen communication for industrial automation networks

The CANopen interface of the UC-CANOPEN-AD16-16/18 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-AD16-16/18 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 CANopen A/D module for reading voltage signals 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.

Precise data acquisition with 16 analog inputs

The 16 galvanically isolated A/D inputs of the UC-CANOPEN-AD16-16/18 enable reliable acquisition of analog signals such as voltage and current. Typical sensors include temperature, pressure, or humidity sensors.
Thanks to versatile measurement ranges (0–5 V, 0–10 V, ±5 V, ±10 V, or optional current measurement) and high resolution, the IoT Analog Converter is particularly suitable for industrial measurement tasks with high demands for accuracy, stability, and flexibility.

Compact DIN rail design with modular system integration

Das CANopen A/D module for reading voltage signals 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-AD16-16/18 wird dabei nahtlos in diese T-Bus-Struktur eingebettet, wodurch eine skalierbare und systematisch aufgebaute Netzwerktopologie entsteht.
Zusätzlich verfügt das CANopen A/D module for reading voltage signals 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.

User Benefits and Practical Application

The UC-CANOPEN-AD16-16/18 offers a practical solution for industrial control and monitoring tasks. Its rugged, galvanically isolated electronics ensure reliable operation, while the documentation, drivers, and ICT diagnostic tool enable quick integration. Thanks to regular updates and direct developer support, the module remains operational over the long term and supports sustainable planning in professional environments.
