■
Overview
The SITRANS LU AO Analog Output Module provides remote
analog output for the measurement points of the SITRANS LU10
level monitor.
■
Benefits
• Analog outputs can be up to 1 500 m (5 000 ft) from the
SITRANS LU 10
• Analog outputs can be per transducer and/or average of 2 or
more
■
Application
The operation of the SITRANS LU AO is programmed via the
SITRANS LU10. The only on-board settings are for bank selec-
tion and output testing.
The SITRANS LU AO can provide up to 10 analog outputs (each
sharing a common negative bus which is electrically isolated
from ground).
