Beckhoff C6525-0070 | Fanless built-in Industrial PC
C6525-0070 | Fanless built-in Industrial PC
The C65xx Industrial PC series is designed to be installed in the panels of the control cabinet or in the rear panel of a control housing or console housing. The heat sink of the Industrial PC is fed to the outside through a suitable cut-out in the control cabinet or housing panel. Power dissipation from the processor and chipset takes place directly to ambient.
Integrated seals provide for an IP65 closure.
This enables high thermal stability and at the same time fanless operation. Industrial PCs of type C65xx can hence be constructed completely without rotating parts.
Industrial design
If the C65xx built-in PC is combined with a Beckhoff Control Panel, the result is a fanless Panel PC that enables operation up to an ambient temperature of 45°C.
The compact housing is equipped with a 3½-inch motherboard for Intel® Celeron® or Core™ i3/i5/i7 of the latest generation. All of the PC’s connectors are located on the top side of the housing.
Maximum data availability and data security
The PCs of the C65xx series are supplied with an integrated power supply unit with 24 V DC input voltage, optionally with integrated uninterruptible power supply (UPS). A battery pack can be connected externally and installed on a DIN rail close to the PC.
Scalable performance

C6525-0070
Industrial PCs from this series, combined with the Beckhoff Control Panels as an operating unit, produce a powerful control platform for machine construction and plant engineering – in particular with the TwinCAT automation software running on Windows 10 IoT Enterprise.
