BL211 PROFINET I/O System

BLIIOT Profinet Coupler BL211 featuring plug-and-play installation without the need for tools and emphasizing stability as a primary characteristic. It is designed with industrial-grade components and complies with EMC (Electromagnetic Compatibility) and EMI (Electromagnetic Interference) testing standards. The BL211 coupler provides dual Ethernet ports to support switch cascade functionality. It supports the standard Profinet IO Device protocol and includes 1 RS485 interface, enabling Modbus RTU to Profinet protocol conversion.

The Profinet Coupler BL211 supports RT (Real-Time) mode with a minimum communication cycle of 1ms. It can handle a maximum input and output of 1440 bytes each and can be expanded with up to 32 modules from the N-series, featuring various functionalities including DI (Digital Input), DO (Digital Output), AI (Analog Input), AO (Analog Output), PWM (Pulse Width Modulation), high-speed pulse counting, thermocouples, and more.

Using a high-speed backplane bus, the coupler can support up to 32 slave stations with a maximum scan cycle of 10ms when fully loaded. It includes built-in Profinet diagnostic functions for real-time monitoring of IO module communication status and provides a 2000mA driving circuit for IO modules.

The Profinet I/O system BL210 is compatible with mainstream PROFINET master stations such as Siemens S7-1200, S7-1500, Codesys, and others. It features a stable and reliable snap-in connection structure with separate wiring terminals from IO modules, allowing for tool-free and plug-and-play installation. The coupler also incorporates an ultra-thin design concept, making it an excellent choice for future industrial automation solutions.
