Functional Features

WC703 NAT Coupler

WC703 NAT Coupler (NAT Conversion Gateway) is suitable for network communication and data collection of PLC, HMI, CNC, DCS, MES, etc. in production networks. It integrates cross-segment isolation and IP conversion functions. Meanwhile, it supports network segment isolation and NAT conversion for more than 2 devices (e.g., PLC, CNC). For multiple devices in the workshop with IP addresses of different network segments, they can be unified into the same network segment to enable cross-segment access such as online programming, data collection, and remote management of devices (e.g., PLC, CNC).
(1) Solves the problem that newly purchased devices cannot access the network due to unmodifiable IP addresses.
(2) Resolves communication failure between devices of different network segments via NAT conversion.
(3) Achieves unified IP planning and management of production networks through IP renaming.
(4) Hides the real IP of devices to prevent network attacks via IP renaming.
(5) Enhances resistance to network interference and attacks effectively through firewall segment isolation and port restriction.

Safe isolation, Reliable protection

Network isolation and protection are realized through various mechanisms such as firewall, internal and external network isolation, equipment IP hiding and encryption, so that your equipment can be safely accessed as you like.

Industrial Grade Features

Support 6V~35V wide voltage power supply, -20℃~70℃ industrial grade wide temperature design, anti-electromagnetic interference, adapt to more application sites with power supply requirements and temperature requirements.
1）Metal shell, protection grade is IP30.
2）EMC grade indicators reach level 3.
3）The Ethernet port supports 1.5KV isolation transformer protection.
4）Anti-electromagnetic interference.
