THE CONTROLLER IS EQUIPPED WITH A MICRO-CONTROLLER with 204 MHz for signal processing and a co-processor, which handles the I/Os and control processes. eControl nano can be operated over a 3,5-inch touch display. The front-installation frame with an integrated recirculating seal provides front-side IP67 protection. On memory side there are 1 MiB of Flash memory, a remanent memory with 32 KiB, and a micro-SD slot for up to 32 GiB of additional storage volume. It measures 163,5 mm x 117,5 mm x 50 mm.

The fan-less system is equipped with two CAN interfaces according to DIN 11898, of which one CAN channel is galvanically isolated. Data rates up to 1 Mbit/s are possible. Moreover the control unit has an Ethernet, EIA-232 (TTL), and USB interface, as well as four electrically isolated digital inputs and relay outputs. An integrated temperature sensor, real-time clock, and power fail detection are also implemented.

The programming of the controller is done in C (a HAL is available). Free configuration, parameterization, and programming possibilities are given. With emWin from Seeger, libraries for a graphical user interface (GUI) are available. Optionally the controller can also be programmed with the runtime system Codesys V3 according to IEC 31131-3.

The controller provides multiple applications in industrial environments and supports control tasks. Possible applications for the controller can be found in automation, machinery control, or as a central control unit, optionally with CAN master functionality.
