2. INTRODUCTION TO
BT200
The BT200 BRAIN TERMINAL is a portable terminal
used in a 4 to 20 mA DC signal line connected to a
BRAIN instrument (*1).
The 4 to 20 mA DC signal line between the BT200
and the BRAIN instrument can be superimposed with a
communication signal to achieve two-way communica-
tion.
Working as a master, the BT200 Permits:
1. Setting and changing parameters for the BRAIN
instrument
2. Monitoring PV and MV values and self-check
information on the BRAIN instrument, and
3. Directing the BRAIN instrument to enter the
constant current output mode.
(*1) BRAIN instrument
Any instrument in support of BRAIN communi-
cations, including field instruments, such as
differential pressure and pressure transmitters,
vortex flow meters, magnetic flow meters and
temperature transmitters, and CENTUM signal
conditioners (SC).
