Manufacturer : Honeywell Model Number : 51309276-150 Product type : High Performance I/O Link The I/O Link Interface Processor is the HPMM interface to its I/O Subsystem. The I/O Subsystem consists of the redundant I/O Link and any combination of up to 40 individual or redundant I/O Processors. These I/O Processors handle all field I/O for data acquisition and control functions. The I/O Processors provide such functions as engineering unit conversion and alarm limit checking, independent of the High Performance Process Manager Module. This architecture provides assured, deterministic control processor performance.
