Rosemount 848L Logic Transmitter
with FOUNDATION™
fieldbus
Innovative Logic Transmitters
Integrates discrete
I/O into a FOUNDATION fieldbus H1 segment
Reduces installation and
maintenance costs with a single network for analog
and discrete devices
Easily configured with the
same DD-based software used for other FOUNDATION fieldbus devices
Higher availability through
logic execution independent of a central controller
Handles demanding applications with fast
embedded logic execution
Discrete I/O Fieldbus
Solutions
Mounts
Anywhere - Field Hardened
Logic Block allows up to 20 Boolean
equations
Reduces discrete I/O
wiring
Reduces need for
discrete I/O bus
Provides user-configurable logic
capabilities which reduces load on DCS and provides
faster response.
Logic capabilities allow outputs to be controlled via 1
or more input status or inputs from another device
on the network.
Communicates up to 128 digital inputs on two wires
- Sixteen 848Ls per FOUNDATION
fieldbus segment
- Eight inputs per 848L
Provides 64 digital outputs (1.0 amps maximum
per output)
- Sixteen 848Ls per FOUNDATION
fieldbus segment
- Four digital outputs per 848L
Industry Leading FOUNDATION
fieldbus Technology
8 Discrete Inputs and 4 Discrete Output blocks communicate
individual input or contact status
1 Multiple Discrete output function block
to efficiently communicate all 4
outputs at once
1 Multiple Discrete input function block
to efficiently communicate all 8 inputs at
once
Backup Link Active Scheduler (LAS) ensures
measurement availability
Logic in the transducer block provides
AND, OR, XOR and NOT logic functionality plus
edge triggering, timer functionality,
shifting, and latching capabilities
