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

Contec CPS-COM-2PD - 2x RS-422A/485 Serial Port CONPROSYS I/O Model
Key Features
CONPROSYS Modular I/O Model
Provides 2 extra RS-422A/485 serial ports
Full duplex/half duplex support
2 - 921,600bps support
200V DC bus isolation
-20 to +60°C operation


Contec's CPS-COM-2PD is an extension COM port that performs serial communication with external device(s) and operates along with the stack type controller of our CONPROSYS series. CPS-COM-2PD has 2 channels of RS-422A/485 communication port.

CPS-COM-2PD is designed for use with the CPS-MCS341-DS1-111 based CONPROSYS modular unit - this I/O unit provides an extra two RS-422A/485 serial ports to this base unit.

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-COM-2PD has 2 RS-422A/485-compliant serial ports. Baud rates from 2 to 921,600bps can be set per each 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
  • The product has the LED for an operation check, which helps you visually confirm the communication status of serial interface
  • Contec designed this product without  electrolytic capacitors, which provides for a longer lifetime
