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)
