Model 1700 and 2700 Transmitters
Output Wiring – Model 1700/2700 Analog Transmitters
Note: If you will configure the transmitter to poll an external temperature or pressure device, you
must wire the mA output to support HART communications. You may use either HART/analog
single-loop wiring or HART multidrop wiring.
It is the user’s responsibility to verify that the specific installation meets the local and national safety
requirements and electrical codes.
