8521-LC-MT MOST Ethernet Bus Interface Module 

The Ethernet BIM incorporates a rigorous redundancy model, HART® capability and a fault tolerant Ethernet implementation to manage communications on the process network and deliver reliable system operation in your application. Process I/O™ is a field-mounted distributed I/O system that provides an intelligent interface between field-mounted instrumentation and the Host system. Process I/O™ interfaces to virtually all process signals including HART®, providing a complete solution for your I/O needs. The complete platform has an environmental specification capable of surviving conditions out in the plant. It is built for harsh process applications, being shock and vibration resistant, operating over the industrial -40°C to +70°C temperature range that is typically associated with field transmitters, and meeting ISA’s stringent G3 corrosion resistance requirements. The EBIM and I/O components can all be mounted directly in Division 2/Zone 2 hazardous areas and, when required, can provide a cost effective intrinsic safety solution. Because the system can be mounted in the field, it can also provide extensive cost savings by eliminating the need to wire all sensors back to a central controller. With the
EBIM and its I/O mounted in the field, the only wiring back to a control room is the high-speed network.
