For the model with optional suffix code /DR:
Remote input with direct input (E1-terminal area)
can be used when
UT55A suffix code: Type 2 = 1, 2, 4, 5, or 7 and
with optional suffix code /DR;
UT52A suffix code: Type 2 = 1 or 2 and
with optional suffix code /DR.
However, DI16 is to be deleted.
Switch to AUTO when
Loop-1 PV input burnout
or A/D error occurs.

Loop-2 parameters
Universal input (E1-terminal area) can be used
when UT55A/UT52A optional suffix code /U1.
However, DI16 does not exist.
(For Standard model)
Remote input can be used when UT55A suffix code: Type 2 = 7.
(For Detailed model)
Remote input can be used when UT55A optional suffix code /A2.
(For Standard model) UT55A suffix
code: Type 2 = 1, 2, 4, 5, or 7; UT52A
suffix code: Type 2 = 1 or 2 is necessary.
(For Detailed model) UT55A/UT52A
optional suffix code /R1 or /RCH1 is
necessary.
(For Standard model) DI16 is equipped
when UT55A suffix code: Type 2 = 1, 2, 4, 5,
or 7; UT52A suffix code: Type 2 = 1 or 2.
(For Detailed model) DI16 is equipped
when UT55A/UT52A optional suffix code
/R1 or /RCH1.
