Contec CPS-DIO-0808BL - Digital I/O CONPROSYS I/O Model

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


Contec CPS-DIO-0808BL is an extension module with isolated digital input and output interface and operates along with the stack type controller of Contec's CONPROSYS series. CPS-DIO-0808BL has 8 channels of the optocoupler isolated input and output per module. 

CPS-DIO-0808BL is designed for use with the CPS-MCS341-DS1-111 based CONPROSYS modular unit - this I/O unit provides an eight digital input channels and eight digital output channels and has a built in power supply

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.

  • CPS-DIO-0808BL has  optocoupler isolated input 8 channels (supporting current sink output) whose response speed is 200microsec, and optocoupler isolated open-collector output 8 channels (current sink type).
  • You can use all of the input signals as interrupt events and also disable or enable the interrupt in bit units and select the interrupt edge.
  • The power to run the optocoupler is supplied internally.You can decide whether you want to use the internal or external power supply by the use of software.
  • This product has a digital filter to prevent input signals from carrying noise or a chattering. All input terminals can be added a digital filter, and the setting can be performed by software.
  • Zener diodes are connected to the output circuits to protect against surge voltages. The rated output is 35VDC, 100mA to the maximum per channel.
  • Compact design, 25.2 (W) x 94.7(D) x 124.8(H) mm - allows flexibility in installation
  • The product is capable of operating in the temperature between -20 and + 60°C. It can be installed in many environments
  • As the product is not only mounted on DIN rail, but also removable along the slide rails, replacing is simple and easy
  • Contec designed this product without  electrolytic capacitors, which provides for a longer lifetime
