{"id":"beckhoff-cx5120","model_id":"CX5120","name":"Beckhoff CX5120","summary":"The Beckhoff CX5120 is a fanless embedded PC for control cabinet installation. It uses an Intel Atom E3815 single-core processor at 1.46 GHz and provides two Gigabit Ethernet ports, four USB 2.0 ports, and a DVI-I interface. Depending on the ordered operating system and TwinCAT runtime, it can run PLC, motion control, or visualization applications.","study_notes":["The CX5120 has a slot for a CFast card and a microSD card; cards are not included.","Main memory is 2 GB DDR3 RAM and is not expandable.","An integrated 1-second UPS is provided with 1 MB on the CFast card.","Cooling is passive. Diagnostics LEDs indicate power, TC status, flash access, and bus status.","I/O connection is E-bus or K-bus with automatic recognition; E-bus/K-bus current supply is 2 A.","The CX5100 series has a compact design and does not support modular extension modules like the CX2000 series.","Product status is regular delivery, not recommended for new projects; the recommended alternative is CX5330.","TwinCAT 3 platform level is Performance (40).","Optional factory-fitted interfaces include RS232, RS485/RS422, EtherCAT master/slave, PROFIBUS master/slave, CANopen master/slave, and PROFINET RT controller/device.","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.","Max. power consumption is 11 W; with loading UPS it is 18 W.","Operating system options include Windows Embedded Compact 7, Windows Embedded Standard 7, Windows 10 IoT Enterprise editions, and TwinCAT/BSD."],"safety_notes":["Approvals/markings: CE and UL.
