Contec CPS-AI-1608LI - Analog I/O CONPROSYS I/O Model

Built-in high-performance firmware, cloud-compatible modular remote I / O unit


Contec's CPS-AI-1608LI is an extension module with analog input interface and operates along with the CPU module-stack type controller of our CONPROSYS series. It has 8 channels of analog input per module

CPS-AI-1608LI is designed for use with the CPS-MCS341-DS1-111 based CONPROSYS modular unit - this I/O unit provides an eight analog input channels .

You can perform all processes from the development to the operation on a web browser. The functions such as Web monitoring of I/O information, alarm processing by I/O information, task divergence enable you to create a Cloud system at low cost and in a short time.

  • Bus-isolated analog input module providing high precision with 8 channels - This product offers 8 channels of bus-isolated analog input (16bit, 8ch) with high precision. It supports differential input and is capable of accurate measurement of voltage with potential differences
  • Compact Design - Compact design, 25.2 (W) x 94.7(D) x 124.8(H) mm, features flexibility in installation. 
  • Adaptable to a wide range of temperature between -20 and +60°C - The product is capable of operating in the temperature between -20 and + 60°C. It can be installed in the various environments. 
  • Installation easy with two pieces of terminal support and DIN rail - You can remove a terminal connector without a screwdriver so that it can shorten the time of the replacement. As the product can be not only mounted on DIN rail but also is removable along the side rails, replacing is simple and easy as well.
  • Equipped with the LED for an operation check - The product has the LED for an operation check, which helps you visually confirm the communication status of each interface.
  • No electrolytic capacitor - Without an electrolytic capacitor, which has a limited life, we are creating the product with a longer life.
