Appendix A

Specifications

A.1 Functional specifications

The Model 1700 or 2700 transmitter’s functional specifications include:

•Electrical connections

•Input/output signals

•Digital communication

•Power supply

•Environmental requirements

•Ambient temperature effect

•EMC compliance

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 FOUNDATION 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 mm2), or one or two stranded conductors, 22 to 14 AWG (0,34 to 2,5 mm2).

Power connection

The transmitter has two pairs of wiring terminals for the power connection:

•One pair of wiring terminals accepts AC or DC power

•One internal ground lug for power-supply ground wiring

Screw terminals accept one or two solid conductors, 14 to 12 AWG (2,5 to 4,0 mm2), or one or two stranded conductors, 22 to 14 AWG (0,34 to 2,5 mm2).

Service port connection

The transmitter has two clips for temporary connection to the service port.

Output Wiring – Intrinsically Safe

Output Wiring – Configurable I/O Output Wiring – Fieldbus/PROFIBUS
