CANopen remote EA D/A DAC module * CANopen module with 4/8 analog outputs

Product Description – CANopen remote E/A D/A DAC module

The UC-CANopen-DA4/8-16ISO is a versatile, high-resolution CANopen remote I/O D/A DAC module designed for industrial applications where precise analog output signals are critical. With a choice of four or eight 16-bit D/A channels, the module enables the precise output of voltage signals in various ranges, including 0–5 V, 0–10 V, ±5 V, and ±10 V. The galvanic isolation of the channels ensures maximum operational reliability, prevents interference, and reliably protects connected systems from ground loops.
Thanks to full support for the CANopen standards CiA 301, 305, and 401, the module can be seamlessly integrated into existing networks. Configuration is conveniently performed via rotary coding switches. The robust design, high-quality WAGO connector technology, and the optional system expansion via the DIN-Rail bus make the UC-CANopen-DA4/8-16ISO a reliable solution for long-term industrial projects.
Typical applications include the precise control of valves, motors, or other analog actuators, as well as the simulation of defined process and test signals in laboratory, manufacturing, and test bench environments. The module thus provides a powerful and future-proof foundation for demanding automation and test systems.

Standardized CANopen communication for industrial automation networks

The CANopen interface of the UC-CANOPEN-DA4/8-16 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-DA4/8-16 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 remote E/A D/A DAC module 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-precision analog outputs for industrial control and regulation applications

The UC-CANOPEN-DA4/8-16 provides, depending on the variant, 4 or 8 high-resolution analog outputs designed for demanding automation and control tasks. Each channel features 16-bit resolution, enabling particularly fine and precise signal generation. The outputs on the CANopen remote E/A D/A DAC module can be flexibly operated as voltage or current interfaces and support common ranges such as 0–10 V, ±10 V, and 0/4–20 mA. This allows a wide variety of actuators such as control valves, drives, or process control systems to be precisely controlled.
Thanks to the high conversion speed and stable signal quality, even dynamic control processes can be reliably implemented. In addition, galvanic isolation between output groups ensures robust and interference-resistant integration in industrial environments.

Compact DIN rail design with modular system integration

Das CANopen remote E/A D/A DAC module 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-DA4/8-16 wird dabei nahtlos in diese T-Bus-Struktur eingebettet, wodurch eine skalierbare und systematisch aufgebaute Netzwerktopologie entsteht.
Zusätzlich verfügt das CANopen remote E/A D/A DAC module 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.
