Product Description:

The CX5140-0115 Embedded PC supports industrial automation applications that require space efficiency and reliable I/O handling. Beckhoff provides reliable operation backed by global certifications and standards compliance.

The CX5140-0115 embedded PC supports a maximum of 64 K-bus I/O terminals and can extend up to 255 with an expansion module. It supports up to 65534 E-bus terminals which enhances large-scale integration capability. The PC uses a dielectric strength of 500 V between the supply and internal electronics for operational isolation. The housing provides IP20 protection that supports non-sealed cabinet installations. Dimensions of 142 mm by 100 mm by 92 mm depth support dense layouts. It uses a DIN rail mounting configuration that simplifies vertical panel placement. The approximate weight of the unit is 1095 g. The shock resistance is rated 15 g for 11 milliseconds and withstands 1000 shocks per axis according to EN 60068-2-27. The PC has vibration resistance from 10 Hz to 58.1 Hz at 0.15 mm displacement and 2 g acceleration up to 500 Hz. It operates reliably between -25°C to +60°C and stores safely between -40°C and +85 +85°C. The humidity tolerance is up to 95 percent non-condensing. Certifications include CE and UL with optional ATEX, IECEx, and DNV GL compliance for global system deployment.

The CX5140-0115 embedded PC uses an internal power separation of 500 V that isolates system electronics from power supply variations. The PC supports a total I/O terminal load of 2 A on E/K-bus and 10 A through power contacts. It supports both K-bus and EtherCAT terminal compatibility, which ensures long-term flexibility for I/O adaptation. The design suits extended environments with high mechanical demand and is well-equipped for advanced control frameworks. It performs within embedded systems that require multi-terminal integration and ensures uninterrupted field data acquisition and processing.
