The IL-NT-RS232-485 is a highly reliable, dual-port communication interface module engineered specifically for InteliLite NT series industrial controllers. This plug-in expansion card seamlessly integrates both RS232 and RS485 communication protocols, enabling robust local configuration and remote monitoring capabilities for generator sets and industrial systems. It is equipped with a standard male DB9 connector for direct RS232 interfacing and a secure 3-position green screw terminal block for long-distance RS485 networking. To ensure superior signal integrity and protect sensitive controller components from electrical noise, the board incorporates a TRACO POWER TME0505S isolated DC-DC converter, providing full galvanic isolation. The module is designed for quick installation, utilizing a robust pin header strip to mount directly onto the controller’s mainboard.
