4-20 mA Output Connections
Connections for the 4-20 mA transmitter output are
made to the connector terminals labeled mA OUT.
The 4-20 mA output may be powered internally or
from an external power supply.
Figure 23. 4-20 mA Output Connections
Analog Output Power Supply
If the analog output is not using the 24 VDC supply to
power the output loop, it can be used for other things.
The I+ Terminal is the +24 V and the R terminal is the
return.

F4 Digital Input Connections
A digital input, F4, is standard on the meter. This
digital input should be connected with a normally
open contact across F4 and COM, or with an active
low signal applied to F4. It can be used to operate the
tare function, for remote operation of front-panel
buttons, to acknowledge/reset relays, or to reset
max/min values. See
capabilities.
