Sfera Labs Strato Pi Max: an industrial controller built with a Raspberry Pi CM4 or Zymbit SCM for DIN rails

Sfere Labs Strato PI Max

Sfera Labs has recently launched two new industrial DIN rail controllers, the Strato Pi Max XS and the Strato Pi Max XL.. These are equipped with a Raspberry Pi CM4 or the Zymbit Secure Compute Module (SCM), and offer various RAM and eMMC flash configurations, with or without wireless connectivity. They also incorporate a Raspberry Pi RP2040 microcontroller to manage tasks such as boot sequence control and power management, and allow connections to the CM4 module via I²C, USB and UART.

The main difference between the XS and XL modules is that the XL supports four additional expansion modules, while the XS has been designed with core features in mind.

Additionally, the company has launched Optional modules to enhance industrial controller capabilities Strato Pi Max. These include the X2-Series Digital I/O, UPS, CAN and Dual RS-485, RS-232 and RS-485 expansion cards, as well as the Swissbit Industrial SSD. The controller includes a shielded 10-50 VDC power supply, internal cooling, temperature sensors, an accurate real-time clock with backup, a 3-axis accelerometer, and a variable pitch buzzer. It's not the first Raspberry Pi CM4-based DIN rail controller we've covered, as companies like EDATEC and Techbase also offer some models.

The starting price of the Strato Pi Max XS module, with 2GB of RAM and 16GB of eMMC, is €425. The version with all the features, including the wireless module, is priced at €959. For the Strato Pi Max XL, the base model with CM4 Wireless, 2GB of RAM and 16GB of eMMC starts at €525, and the fully equipped version reaches €1.085. Expansion card prices vary from €85 to €150. All of these items are currently available for pre-order and are expected to be available in June 2024. You can find more information on the subject at your product page...
