This is the DIN rail mountable version of the Pi-Spi-8DI Isolated Digital Input I/O Module.
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 I/O 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.
Specifications:
- Two 16 Pin GPIO Ports (Power, SPI, I2C and 5 Chip Selects)
- 5 VDC 0.5A Switching Power Supply (9 to 24 VDC Input)
- 3.3VDC LDO regulator
- Terminal Blocks are rising clamp cage screw type (no leaf springs)
- Blue LED indicators for power
- MCP23S08 I/O Expander with 4 Address Selects
- Green LED ON Indicators for each Input
- All inputs are optically isolated and can accept either VDC or VAC inputs, Max 24V
- PCB Dimensions: 2.7" Wide x 3.42" Long
Mounting Styles:
Each PI-SPI-DIN I/O Module has three mounting styles available:
PCB
PCB on DIN rail mounting clips
DIN Enclosure
Dimensions: 3.51" Long x 2.975" Wide x 1.11" High
DIN rail enclosures are available in three colours: Black (Standard), Blue (Custom), and White (Custom). Enclosures are fabricated using PETG Plastic.
PI-SPI-DIN-8DI Accessories :
All PI-SPI-DIN I/O Modules come complete with interconnect ribbon cables and all necessary hardware based on enclosure style.
