Model 1700 and 2700 Transmitters
Specifications
Core processor connection
The transmitter has two pairs of wiring terminals for the 4-wire connection to the core processor:
One pair is used for the RS-485 connection
One pair is used to supply power to the core processor
Plug connectors accept stranded or solid conductors, 24 to 12 AWG (0,2 to 2,5 mm
2
).
FISCO and FNICO approval
Model 2700 transmitters with F
OUNDATION fieldbus and PROFIBUS-PA are either FISCO or FNICO
approved depending on their output code:
Transmitters with output code E (intrinsically safe F
OUNDATION fieldbus) or output code G
(PROFIBUS-PA) are FISCO approved with the following entity parameters:
-Ui = 30 V
- Ii = 380 mA
-Pi = 5.32 W
- Ci = 0.0002 µF
-Li = 0.0 mH
Transmitters with output code N (non-incendive F
OUNDATION fieldbus) are FNICO approved
A.1.2 Input/output signals
Input signal from sensor
4-wire remote: one intrinsically safe 4-wire mating connector
9-wire remote: two intrinsically safe terminal blocks with 3 sockets and one intrinsically safe
terminal block with 4 sockets (only 3 sockets are used)
Remote core processor with remote transmitter:
- Core processor: two intrinsically safe terminal blocks with 3 sockets and one intrinsically
safe terminal block with 4 sockets (only 3 sockets are used)
- Transmitter: one intrinsically safe 4-wire mating connector
Model 1700/2700 transmitters with non-intrinsically safe analog outputs option board
(output option code A)
One 4–20 mA output
Not intrinsically safe
Internally powered (active)
Isolated to ±50 VDC from all other outputs and earth ground
Maximum load limit: 820 Ohms
Model 1700 can report mass flow or volume flow; Model 2700 can report mass flow, volume
flow, density, temperature, or drive gain; transmitters with the petroleum measurement
application (API) or enhanced density application can also report standard volume flow and
density at reference temperature
Linear with process from 3.8 to 20.5 mA, per NAMUR NE43 (June 1994)
