12 Specifications FSM4000
64 S4 D184B122U02
Contact input Active as operating contact (normally open)
optocoupler specifications:
„On“ 16V ≤ U
KL
≤ 30 V DC,
„Off“ 0V ≤ U
KL
≤ 2 V DC, R
i
0= 2 kΩ
The following functions can be assigned:
Ext. zero return, ext. totalizer reset
Contact output Passive as operating contact (normally opened or closed)
Optocoupler specifications:
„Closed" 0 V ≤ U
CEL
≤ 2 V, 2 mA ≤ I
CEL
≤ 220 mA
„Open“ 16V ≤ U
CEL
≤ 30 V DC, 0 mA ≤ I
CEH
2 mA
The following functions can be assigned:
Forward/reverse flow direction signal, limit alarms (max. or min.),
general alarm, empty pipe
Communication HART-Protocol over current output or
PROFIBUS PA
Data security Using FRAM, all data stored for a 10 year period without
supplementary power when the power is turned off or interrupted.
Additional security using a serial internal and external FRAM for data
exchange for data storage of process information and instrument
values.
Display 4-line lighted graphical display with a 4x16 character dot matrix display
indication. User selectable values for display in each line.
Standard is 2-line; 1st line „large“, 2nd line „small“.
Interference resistance (EMC) Per EN 61326 and NAMUR NE21.
Retrofit For older flowmeter primaries (Series DS2_, DS4_, 10DS3111,
10DI1425 and 10D1422) the system can be operated using
Converter S4.
