Loop-Powered
Backlight Option
Factory installed only. Powered directly
from the 4-20 mA loop, no batteries
required. Backlight can be enabled or
disabled via alternative wiring of terminal
block. The display brightness will increase
as the input signal current increases.
Input
Overload
Over current protection to 2 A max.
HART
Transparency
The meter does not interfere with existing
HART communications; it displays the 4-20
mA primary variable and it allows the HART
communications to pass through without
interruption.
The meter is not affected if a HART
communicator is connected to the loop.
The meter does not display secondary
HART variables.
