{"id":"beckhoff-cx8280","model_id":"CX8280","name":"Beckhoff CX8280","summary":"The Beckhoff CX8280 is an embedded PC with an Arm Cortex-A53 dual-core processor at 1.2 GHz and 1 GB LPDDR4 RAM. It provides one Gigabit Ethernet interface, one USB 3.0 interface, and a 9-pin D-sub bus interface with one RS232 and one RS485 serial port. It runs Beckhoff RT Linux with TwinCAT 3 runtime (XAR) and accepts E-bus or K-bus terminals.","study_notes":["Two serial interfaces are on a 9-pin D-sub socket: one RS232 and one RS485; they are not bound to a particular protocol.","E-bus or K-bus terminals can be attached as required; the CX8280 automatically recognizes the connected I/O system at startup.","TwinCAT 3 programming is via the bus interface or the additional Ethernet interface; TwinCAT 3 licenses must be ordered separately.","Operating system is Beckhoff RT Linux; control software is TwinCAT 3 runtime (XAR) from TwinCAT 3.1 Build 4026.","The microSD card is not included and requires a minimum capacity of 16 GB; an integrated 1-second UPS uses 1 MB on the microSD card.","Internal capacitor-buffered real-time clock stores time and date for more than 21 days.","Dimensions are 71 mm x 100 mm x 73 mm; cooling is passive.","Current supply for E-bus/K-bus is 2 A; maximum E-bus/K-bus power is 10 W (5 V/max. 2 A).","Maximum power consumption is 4 W, or 7.5 W with UPS loading.","Vibration/shock resistance conforms to EN 60068-2-6/EN 60068-2-27; EMC immunity/emission conforms to EN 61000-6-2/EN 61000-6-4.","Product announcement with estimated market release in the 1st quarter of 2027.","TwinCAT 3 platform level: Economy (20)."],"safety_notes":["Approvals/markings: CE, UL.","Storage temperature: -40 to +85 °C.","Relative humidity: 95%, no condensation."],"sources":[{"url":"https://www.beckhoff.com/en-en/products/ipc/embedded-pcs/cx8200-arm-r-cortex-r-a53/cx8280.html","title":"Embedded PC with Arm® Cortex®-A53 and RS232/RS485","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":9,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"hardware","spec":{"category":"embedded_pc","manufacturer":"beckhoff","controllers":[],"weight_kg":0.22,"ethernet_ports":1,"processor":"Arm® Cortex®-A53, 1.2 GHz","supply_voltage":"24 V DC (-15%/+20%)","power_consumption_kw":0.004,"ip_rating":"IP20","operating_temp_min_c":-25,"operating_temp_max_c":60,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/beckhoff-cx8280","license":"https://creativecommons.org/licenses/by/4.0/"}
