Typically control systems are commissioned with a set number and type of input/output (I/O) cards that can accept data from sensors and instrumentation. Universal I/O definedUniversal I/O, also defined as electronic marshalling, allows for different I/O types to be landed on one card. With FLEXHA 5000 universal I/O, these configurations are enabled by the software, avoiding the need for physical component changes. The FLEXHA 5000 universal card differs by it being one single catalog entry, reducing the need to carry additional inventory. Not all universal I/O is the sameMany control system providers have released universal I/O capabilities, but not all cards are built the same.
