CANopen A/D measurement data acquisition with galvanic isolation * CANopen module with 2 analog inputs

Product Description – CANopen A/D module with galvanically isolated channels for measurement acquisition

The UC-CANopen-AD2-16ISO is a high-precision analog input module designed specifically for industrial applications where reliable and interference-free measurements are critical. With two 16-bit A/D channels, the module enables the precise acquisition of analog voltage and current signals. The ability to capture AD measurement values with galvanic isolation ensures maximum measurement reliability, protects connected systems from interference, and prevents ground loops—a significant advantage in demanding industrial environments.
Thanks to full support for the CANopen standard (CiA 301/305/401), the CANopen A/D module with galvanically isolated channels for measurement acquisition can be seamlessly integrated into existing CAN networks. The flexible selection of various measurement ranges, along with robust galvanic isolation up to 1 kV, enables use in a wide variety of scenarios, from sensitive sensor signals to industrial process variables. The fast conversion rate of 4 µs per channel ensures responsive acquisition even of dynamic signals.
Typical applications include the precise evaluation of temperature, pressure, or flow sensors, as well as the continuous monitoring of critical process values in manufacturing, testing, and automation systems. Thus, the UC-CANopen-AD2-16ISO offers a long-term stable, reliable, and versatile solution for professional measurement and control tasks.

Standardized CANopen communication for industrial automation networks

The CANopen interface of the UC-CANOPEN-AD2-16/18_ISO 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-AD2-16/18_ISO 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 with galvanically isolated channels for measurement acquisition 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.

High-resolution precision for industrial analytical signals

The UC-CANOPEN-AD2-16/18_ISO features two galvanically isolated analog inputs that can be operated with either 16-bit or 18-bit resolution, enabling both robust standard measurements and high-precision signal acquisition. In the 16-bit variant, a wide range of voltage inputs is available, including 0–5 V, 0–10 V, 0–20 V, and 0–40 V, as well as bipolar ranges up to ±40 V. In addition, current signals in the ranges 0–20 mA, 4–20 mA, and 0–24 mA can be measured.
The 18-bit variant is specifically optimized for high-resolution measurement tasks and primarily supports precise voltage measurements in the ±5 V and ±10 V ranges, allowing even small signal variations to be captured with significantly higher accuracy.
Both variants operate with a very high input impedance of more than 500 kΩ, ensuring minimal loading of the measured signals and enabling reliable connection of sensitive sensor sources. The integrated galvanic isolation reliably protects the measurement channels and ensures stable measurement results even in electrically noisy industrial environments.
By combining flexible measurement ranges, high resolution, and precise signal conditioning, the CANopen A/D module with galvanically isolated channels for measurement acquisition is ideally suited for demanding industrial measurement and monitoring applications.

Compact DIN rail design with modular system integration

Das CANopen A/D module with galvanically isolated channels for measurement acquisition 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-AD2-16/18_ISO wird dabei nahtlos in diese T-Bus-Struktur eingebettet, wodurch eine skalierbare und systematisch aufgebaute Netzwerktopologie entsteht.
Zusätzlich verfügt das CANopen A/D module with galvanically isolated channels for measurement acquisition 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.
