Field bus unit is used to provide input from a range of sensors and has a built in digital signal processing capacity with a facility for being programmable

摘要

The unit has a pick up (MA) that is coupled to a sensor (SE) and this provides input to a logic module (LB that incorporates a digital signal processor and a system processor. The module connects with the communication unit (CE) coupled into the field bus system and also controls an analogue module (AE).
