26 Transmitter Configuration and Use: Series 1000 and 2000 Transmitters

Connecting with the 275 HART Communicator or 375 Field Communicator continued

2. Connect the Communicator leads to the transmitter’s primary mA output terminals:

• Model 1700/2700 transmitters: terminals 1 and 2 (see Figure 4-1)

• Model 1500/2500 transmitters: terminals 21 and 22 (see Figure 4-2)

3. The Communicator must be connected across a resistance of 250–600 Ω. Add resistance to the

connection. See Figure 4-1.
