The Beckhoff CX2500-0030 Serial Interface Module (RS232) is designed to expand the communication capabilities of the CX20xx, CX52x0, CX53x0, and CX56x0 Embedded PC series. This module provides a dedicated RS232 port, enabling seamless integration with a wide variety of serial devices and legacy systems still prevalent in industrial environments. Its compact and durable design makes it ideal for applications requiring stable serial communication in demanding conditions.

The module offers two standard 9-pin D-sub connectors, ensuring compatibility with a broad range of industrial devices such as barcode scanners, modems, measurement instruments, and older control systems. By providing industry-standard RS232 communication, the CX2500-0030 supports point-to-point connections, ensuring straightforward and reliable data transfer between Beckhoff controllers and external devices.

One of its advantages is its power supply integration through the system bus. Instead of requiring a separate power source, the CX2500-0030 is powered directly by the CX2100-0xxx power supply modules connected to the host Embedded PC. This simplifies installation, reduces wiring complexity, and ensures seamless operation as part of the CX system family.

The module is engineered for industrial reliability, with a wide operating temperature range from -25°C to +60°C and a storage tolerance from -40°C to +85°C. Its slim 24 mm width and compact dimensions (99 mm x 54.5 mm) make it easy to install within space-constrained control cabinets. Weighing only 205 g, the CX2500-0030 adds minimal load while expanding communication options for the host system.

As part of Beckhoff’s modular architecture, the CX2500-0030 integrates seamlessly into the overall control system. It enables engineers to incorporate devices that rely on serial communication into automation networks without requiring additional hardware converters or gateways. This makes it particularly valuable for bridging the gap between modern EtherCAT-based systems and traditional RS232-enabled equipment.

The rugged build quality ensures reliable performance in harsh industrial environments, supporting continuous operation in manufacturing, logistics, building automation, and process control settings. Its robust connectors and tested reliability make it suitable for applications where communication stability is critical.

In summary, the Beckhoff CX2500-0030 expands the versatility of CX Embedded PCs by adding a reliable RS232 communication interface. With its dual D-sub connectors, system bus power integration, compact form factor, and industrial-grade durability, it provides a dependable and straightforward solution for connecting legacy or third-party serial devices to Beckhoff automation platforms.
