CPI-DI-16L Digital Input Raspberry Pi Expansion Card / 16ch Opto-coupler Isolated Inputs / 200us Response Time / -20-60C Operation

The CPI-DI-16L is a 16-channel digital input expansion card, designed to enhance the functionality of the Raspberry Pi. Contec's CPI series allows you to easily stack up to eight HAT (Hardware Attached on Top) size expansion cards, bringing industrial-grade availability and maintainability to your Raspberry Pi devices.

• Push-type terminal block for easy wiring
• The CPI Series includes a push-type terminal block for convenient, simple connection and disconnection of wired HATs without needing tools or crimping terminals.
• Stacked connection of up to eight cards
• Contec has expanded HAT specifications to include address ID configurability, making it possible to connect up to eight stacked cards. Connection to HATs from other manufacturers is also possible. 
• API compatible with PC expansion cards and Python-compatible API
• Take advantage of API compatibility with Contec's PCIe, USB, and Ethernet-type measurement control devices. Development assets can be reused across multiple platforms. Linux drivers (API-TOOL for Linux) can be downloaded for free from our website along with sample Python and GCC programs, allowing users to begin programming right away.
• Opto-coupler isolated digital inputs (supporting current sink and current source outputs)
• Equipped 16ch of inputs with opto-coupler isolation (from current sink or current source outputs) for excellent noise resistance. Eight channels share one common terminal, and the two common terminals can support different external power supplies.
• Adaptable to a wide range of environments
• The CPI-DI-16L can be powered with an input voltage range of 12-24VDC in operating temperatures between -20 to 60°C, resulting in flexible operation over a wide range of environments.
