X20cDO2633

The X20cDO2633 from B & R Automation is a high-performance module within the X20 Fieldbus Input Output Modules series, designed to deliver reliable digital output control in industrial environments. Powered by an Intel Atom processor and equipped with 512 MB DDR2 RAM alongside 2 GB onboard flash memory, this I/O module supports CAN, Ethernet, and POWERLINK fieldbus options for versatile connectivity. Operating at 24 VDC and featuring an IP20 protection class, it is optimized for DIN rail mounting and provides a compact footprint without compromising durability. The unit’s 3-wire connection type and Triac outputs enable seamless integration with resistive and inductive loads, supporting a wide voltage range of 48 to 240 VAC. Designed for precision and robustness, the X20cDO2633 is ideal for automation systems requiring advanced digital output capabilities.

Technical capabilities of the X20cDO2633 include phase angle control for fine regulation of power delivery, allowing control from 5 % to 95 % with 1 % resolution. The module delivers 2 digital outputs rated for a nominal current of 2 A per channel, summing to 4 A total nominal output, with a maximum channel current of 2.5 A and a summation current of 5 A. It operates across an output frequency range of 47 to 63 Hz and incorporates zero-crossing detection to minimize electromagnetic interference during switching. A built-in varistor for overvoltage protection between L and N safeguards connected loads, while leakage current remains capped at 2.4 mA at 240 VAC.

Operational features reinforce reliability and simplify maintenance: the module consumes only 0.6 W bus power, with an additional 6 W dissipation under resistive actuator loads. Status indicators provide real-time feedback on module status, operating state, and individual I/O functions. Comprehensive diagnostics—accessible via software—cover voltage monitoring, open-circuit detection, and varistor health. The unit supports both L-switching and efficient thermal management under IP20 conditions, ensuring stable performance in demanding plant environments.

Integration into control architectures is straightforward thanks to its DIN rail mounting capabilities in both horizontal and vertical orientations. The module’s ambient temperature range extends from –25 °C to 60 °C horizontally and –25 °C to 50 °C vertically, accommodating diverse installation settings. Robust insulation testing (1 500 VAC channel-to-bus and channel-to-ground, 2 000 VAC channel-to-internal I/O) reinforces safety and compliance with industrial standards. As a versatile I/O module, the X20cDO2633 integrates seamlessly into automated manufacturing, process control, and machine building applications where precise, reliable digital outputs are essential.
