The 88970270 is an XN05 Ethernet protocol TCP/IP Modbus extension module designed to connect one or several Millenium 3 controllers to a touch screen, supervision PC, or network gateway. This sandwich communication extension operates via 24 V power supply from the controller and supports standard Modbus TCP/IP protocol with static or dynamic (BootP server) addressing capabilities. The module enables exchange of input/output states and internal values, as well as updating date and time across a group of Millenium 3 controllers, with a maximum network distance of 100 m between controllers. Operating over a temperature range of 0°C to +55°C (+40°C in non-ventilated enclosures) and certified to UL and CSA standards, this module is ideal for industrial automation applications requiring networked communication and centralized supervision of multiple controllers.
