A Compact Controller Based on Raspberry Pi
The new RevPi Compact from KUNBUS is the latest addition to the RevPi product suite of industrial PCs. It is a powerful and cost-effective compact controller based on Raspberry Pi Compute Module 3+ and comes with extensive connection options and functions.
Sensors and/or actuators can be connected via 8 digital and analog inputs as well as 8 digital and 2 analog outputs. Thanks for two Ethernet ports, with unique MAC addresses, the device can be simultaneously integrated into two different networks. Lastly, 4 USB ports and a 4-pole RS485 interface are also included.
The low profile design allows the device to be installed in sub-distribution systems, which are commonly found in building automation. The operating system used is an adapted Raspbian with a real-time patch. Individual applications can be programmed via Node-RED, Python or directly in C. The popular industrial protocols Modbus RTU and Modbus TCP are supported as standard. Those who do not want to program themselves can optionally use professional soft PLC and SCADA software for control and visualization.
