Contec CPS-PCS341EC-DS1-1201 - CODESYS EtherCAT Master

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


Contec's CPS-PCS341EC-DS1-1201 is an EtherCAT Master controller with isolated digital input and output (Input: 4ch, Output: 4ch), RS232C, and LAN interface. You can affix the stacking devices of our CONPROSYS series as you desire. (Up to 32 devices). 

  • This product features the CODESYS Soft PLC. CODESYS is a device-independent-PLC-programming system that is complied with the IEC 61131-3 standard and supports all standard programming languages such as ST or LD.
  • EtherCAT is a strong, efficient real-time Ethernet field bus system with an open protocol.
  • OPC UA (Unified Architecture) is an advanced model of OPC specifications, which presents refined capability of transmitting and receiving semantic description data. OPC-UA is a platform independent standard based on TCP.
  • Compact design, 44.7 (W) ×94.7 (D) ×124.8 (H) mm, features flexibility in installation.
  • The product is capable of operating in the temperature between -20 and + 60°C. It can be installed in the various environments.
  • The product contains the ARM®Cortex®-A8 processor (600MHz) and the DDR3 512MB system memory.
  • You can remove a terminal connector without a screwdriver so that it can shorten the time of the replacement. As the product is mounted on the DIN rail, removing and replacing are easy as well.
  • Without an electrolytic capacitor, which has a limited life, we are creating the product with a longer life.
