OVERVIEW

Transmitter

The 848L provides a cost effective field mounted interface for discrete inputs

 

and outputs on a Foundation Fieldbus H1 network. The 848L allows you to

 

leverage the fieldbus network to reduce discrete input and output wiring and

 

eliminate the need for a separate bus for discrete inputs and outputs. The

 

848L can communicate with other devices on the segment to provide logic

 

interactions independent of any upper level controller.

 

The 848L also has logic capability allowing it to independently control outputs

 

based on the state of one or more of it's inputs or discrete signals from other

 

devices on the network. A Logic Block allows for up to 20 Boolean equations,

 

8 Inputs, and 4 Outputs.
