CPI-CNT-3201I

Overview / Features

This product is an expansion card that adds an counts input interface to the Raspberry Pi. It has one channel of 32-bit up/down counters, allowing external devices such as a rotary encoder and a linear scale to be connected. The pulse signal interface is an opto-coupler isolated input.

• 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 the need for tools or crimping terminals.
• Stacked connection of up to 8 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. * Use a CONTEC RAS function expansion card (CPI-RAS) for stable power supply with stacked connections.
• API compatible with PC expansion cards and Python-compatible API
  • Take advantage of API compatibility with CONTEC PCI Express, PCI, USB, and Ethernet-type measurement control devices. Development assets can be reused across multiple platforms. Linux driver (API-TOOL for Linux) can be downloaded for free from the company’s website along with sample Python and GCC programs, allowing users to begin programming right away.
• 32-bit up-and-down counter
  • The 32 bit up-and-down counter could have four channels and up to 500kHz maximum speed pulse input. Moreover, it can count 2-phase signals and mono-phase signals such as a rotary encoder and a linear scale.
• Opto-coupler bus isolation
  • As the GPIO 40pin connector on Raspberry Pi is isolated from the input and output interfaces by opto-couplers, this product has excellent noise performance.
• Adaptable to a temperature range between -20 to 60°C
  • The product is capable of operating in the temperature between -20 to 60°C. It can be installed in the various environments.
