RevPi Core S

SKU #: KU-PR100359, KU-PR100360, KU-PR100361
by KUNBUS

A Robust Open Source IPC Based on Raspberry Pi 

The new RevPi S and SE series are based on the brand-new Raspberry Pi Compute Module 4S. The series are an intermediate step between the RevPi Core 3+ series and the RevPi 4 series. The RevPi Core S is the updated version of the RevPi Core 3+ based on the Compute Module 3+. The Core S supports all gateways, including the I/O expansion modules as well as the gateway expansion modules.

The quad-core RevPi Core S comes equipped with the Raspberry Pi Compute Module 4S for the ultimate in high performance for complex tasks such as image processing. RevPi Core S comes equipped with an adapted Raspbian Jessie with an RT patch. In addition to quadrupling the number of CPUs (Broadcom BCM2711), improvements to this latest version include 1 GB of RAM and 1.5 GHz clock rate, and 8 or 32 GB of eMMC flash memory.

Consisting of open hardware and software, the RevPi Core S IPC meets the EN61131-2 standard. Its modular design allows for it to be enhanced with digital and analogue I/O modules as well as appropriate fieldbus gateways. Mounted in a DIN rail housing, the RevPi Core S has USB, ethernet and HDMI ports, and runs on the standard industrial 24-volt power supply.

Lastly, the RevPi Core S has Master and Slave capabilities for the two highly popular communication protocols Modbus TCP and Modbus RTU. Expensive external gateways are no longer required. The RevPi Core S is therefore an economical and logical choice for use as an industrial PC.
