The 6B Series of modules and boards provides the hardware needed to implement a flexible, distributed monitoring and control application. By selecting only the modules and interfaces needed and connecting them via RS-485, the data acquisition and control strategy can be designed for optimum location of the I/O as well as minimizing sensor runs. The modularity and configurability of the 6B Series also makes them very cost effective. * 24 Channel Digital I/O * RS-485 Interface or RS232 Versions
