Contec Co., Ltd. (Headquarters: Nishi-yodogawa-ku, Osaka; President: Kazuyoshi Nishiyama) has developed two new CONPROSYS nano series EtherNet/IP Coupler Units, the CPSN-EOB471EI-41 and CPSN-EOB471EI-81. These new products are available to order from April 23, 2026.

Model Product Name
CPSN-EOB471EI-41 CONPROSYS nano Series EtherNet/IP Coupler Unit (4 slots)
CPSN-EOB471EI-81 CONPROSYS nano Series EtherNet/IP Coupler Unit (8 slots)

The new coupler units can be equipped with four or eight CONPROSYS nano series I/O modules, enabling the construction of remote I/O systems as EtherNet/IP adapter devices.

Main Features

  • Connects to EtherNet/IP-compatible PLCs and industrial controllers, operating as an EtherNet/IP adapter. Enables integration into EtherNet/IP networks.
  • Support for a wide variety of CONPROSYS nano series I/O modules

    These products support flexible I/O module expansion using CONTEC’s diverse lineup of CONPROSYS nano series modules to match the required functions and system configuration.

  • Operating temperature range: −20 to +60°C (−4 to 140°F)

    Both new products support a wide operating temperature range of −20 to +60°C, making them suitable for various environments including inside control panels and equipment.
