{"id":"beckhoff-cx9240","model_id":"CX9240","name":"Beckhoff CX9240","summary":"The CX9240 is a DIN rail-mountable embedded PC used as an Ethernet control system for PLC and motion control applications. It runs Beckhoff RT Linux on a four-core 1.2 GHz Arm Cortex-A53 CPU with 2 GB LPDDR4 RAM, two independent 1 Gbit Ethernet interfaces, four USB 3.0 ports and a DisplayPort. The operating system, TwinCAT and user projects are stored on an interchangeable microSD card, and Beckhoff I/O systems connect directly to the CPU module via E-bus or K-bus.","study_notes":["TwinCAT 3 runtime (XAR) requires TwinCAT 3.1 Build 4026 (XAE) or later.","Main memory is 2 GB LPDDR4 RAM and is not expandable.","Boot and storage medium is a microSD card (not included) with a minimum capacity of 16 GB.","I/O connection is E-bus or K-bus with automatic bus system identification.","E-bus/K-bus current supply is 2 A; max power consumption on E-bus/K-bus is 10 W (5 V, max 2 A).","Max power consumption is 7 W, or 12 W while the integrated UPS is loading.","One multi-option interface can be assigned ex factory, e.g. RS232, RS485/RS422, 2x EtherCAT master, EtherCAT slave, PROFIBUS master/slave, CANopen, or a 2-port Ethernet switch.","Diagnostics LEDs: 1x power, 1x TC status, 1x flash access, 2x bus status.","Internal real-time clock is capacitor-buffered with storage capacity greater than 21 days.","Cooling is passive; dimensions are 84 mm x 100 mm x 91 mm (W x H x D).","Integrated 1-second UPS with 1 MB on the microSD card; UPS OCT-capable: no.","TwinCAT 3 platform level Economy Plus (30)."],"safety_notes":["Approvals/markings: CE, UL.","Protection rating IP20.","Operating temperature range -25 to +60 °C; storage temperature -40 to +85 °C.","Relative humidity 95%, no condensation.","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.","Power supply 24 V DC (-15%/+20%), electrically isolated.","Integrated 1-second UPS buffers the supply in case of power failure.","RoHS compliant with exemption; contains lead (REACH SVHC)."],"sources":[{"url":"https://www.beckhoff.com/en-en/products/ipc/embedded-pcs/cx9240-arm-r-cortex-r-a53/cx9240.html","title":"Embedded PC with Arm® Cortex®-A53","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":0.65,"ethernet_ports":2,"processor":"Arm® Cortex®-A53, 1.2 GHz","supply_voltage":"24 V DC (-15%/+20%), electrically isolated","power_consumption_kw":0.007,"ip_rating":"IP20","operating_temp_min_c":-25,"operating_temp_max_c":60,"joints":[],"protocols":[],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/beckhoff-cx9240","license":"https://creativecommons.org/licenses/by/4.0/"}
