A.1.1 Electrical connections
Output connections
The transmitter has two (Model 1700) or three (Model 2700) pairs of wiring terminals for
transmitter outputs.
The Model 1700/2700 with analog outputs option board has one pair of wiring terminals for
digital communications (Modbus or HART protocol on RS-485)
On the Model 2700 with F
OUNDATION fieldbus or PROFIBUS-PA, terminals 3–6 are not used.
Screw terminals accept one or two solid conductors, 14 to 12 AWG (2,5 to 4,0 mm
2
), or one or two
stranded conductors, 22 to 14 AWG (0,34 to 2,5 mm
2
).
Power connection
