1.2 Wiring diagrams
Use the following wiring diagrams to wire the Rosemount 751 Field Signal
Indicator, in series or in parallel, with Rosemount transmitters. Use shielded
cable for best results in electrically noisy environments.
It is recommended that the Rosemount 751 indicator be wired in a series
configuration when the 4-20 mA transmitter does not contain a test terminal.
The Rosemount 751 is designed so the analog or LCD display meter can be
removed from the housing without impacting the integrity of the 4-20 mA
loop. Removal of the entire Rosemount 751 device from the series
configuration will disrupt the loop.
