■
Overview
SITRANS LU SAM Satellite Alarm Module provides up to 20 relay
outputs for the measurement points of the SITRANS LU10 level
monitor.
■
Benefits
• The SITRANS LU SAM can be located up to 1500 m (5000 ft)
from the SITRANS LU10
• Relay outputs can be assigned to any point on the
SITRANS LU10
■
Application
The operation of the SITRANS LU SAM is programmed via the
SITRANS LU10. The only on-board settings are for bank selec-
tion and output testing.
Using a SITRANS LU SAM, you can have two relay outputs for all
ten measurement points, all 20 for a single measurement point
or any combination between the two.
All relays are Form C to allow NO or NC wiring.
