PI-SPI-DIN-8DI Raspberry Pi DIN Rail Isolated Digital Input Interface
This is the DIN rail mountable version of the Pi-Spi-8DI Digital Input Interface.
The PI-SPI-DIN-8DI has 8 inputs that can either DC or AC (Max 24 V) and are optically isolated.
The design is based on the Microchip MCP23S08 IO Expander. Each MCP23S08 has 4 addresses using the same SPI Chip Select line, meaning 4 modules (32 Inputs) can be used simultaneously.
Each module in the PI-SPI-DIN series has two 16 Pin GPIO ports that carry power, SPI, I2C andd 5 Chip Selects from the main PI-SPI-DIN-RTC-RS485 Module. Also, each module has it's own 5VDC switching power supply and 3.3VDC LDO regulator.
Two 16 Pin GPIO Ports (Power, SPI, I2C and 5 Chip Selects)
