Quick Start Guide
2.1 Power supply
The dc power supply should provide power with less than two percent ripple. The
total resistance load is the sum of the resistance of the signal leads and the load
resistance of the controller, indicator, and related pieces. Note that the resistance
of intrinsic safety barriers, if used, must be included.

Voltage (V dc)
The Field Communicator requires a minimum loop resistance of 250Ω for communication.

Note:
A check (✓) indicates the basic configuration parameters. At a minimum, these parameters should
be verified as part of the configuration and startup procedure.
