VP Process Inc has just released a new series of Raspberry Pi DIN rail mountable "Hardened" interfaces. The first to be released is the PI-SPI-DIN-RTC-RS485, which is available in three mounting versions:
DIN Rail Clips
DIN Rail Enclosure
PCB Spacers
and finally a view of the PCB itself:
The basic specifications for the PI-SPI-DIN-RTC-RS485 are:
- Power Input: 9 to 24 VDC
- 5VDC @ 2.5A (Max 3Amp) Power Supply
- RS485 Output via RJ45 connector and Terminal Block
- 2 GPIO connectors - 1 internal for Raspberry Pi, 1 external for peripherals
- 1 PI-SPI-DIN connector (16 Pin) for PI-SPI-DIN series (power, SPI, I2C and 5 Chip Enables)
- Real Time Clock (I2C) Microchip MCP7940 with Battery Backup
More information for this interface can be found here:
Peripheral units to be released:
PI-SPI-DIN-8AI - 8 channel 4-20 mA input module
PI-SPI-DIN-4KO - 4 channel Relay Output Module with 2 Amp contacts
PI-SPI-DIN-8DI - 8 channel Digital (Isolated) Input Module
PI-SPI-DIN-4AO - 4 channel 4-20mA Output Module
Each of the modules will have 2 x 16 Pin Ribbon Cable sockets and cables. Each connector and cable will carry power (the main power supply input to the main interface), I2C bus, SPI bus and 5 GPIO lines for Chip Select.
Each peripheral will also be available as a PCB, PCB with DIN Rail Clips or DIN Rail enclosure.
Update March 2018
VP Process Inc has created a launched on GitHub a new set of Python libraries for the PI-SPI and PI-SPI-DIN series of products.
