The internal RAM size is 8 GB; up to 32 GB are also optionally possible. The controller boots from the CFast card and has an internal

128 kB NOVRAM for use as a persistent data memory.

The CX2043 is cooled by a high-quality speed-monitored and speed-controlled fan. The fan cartridge features wireless contacting

and is easy to replace.

Other components from the CX2000 family can be connected via the multi-pin terminals on either side. Up to four modules of the

type CX2500-xxxx can be connected on the left side of the basic CPU module. The connection order is irrelevant. Internally, the

modules are connected via PCI Express® and can be plugged to the CPU in the field.

Modules of the type CX2550 (e.g., hard disks/SSD modules) and a power supply unit of the type CX2100-xxxx can be connected on

the right. The power supply unit supplies power to the entire system of CPU module and all plugged optional components. All

Beckhoff EL and KL terminals can be connected directly to the power supply unit. A compact unit comprising controller and I/O

level is thus created on the DIN rail.

The extended operating temperature range from -25°C to +60°C enables the CX2043 to be used under climatically challenging

conditions.
