In Estimating-type position proportional control, the limiter function
does not work on output operation.
The reverse-signal relay turns on when being limited by low limit.
The direct-signal relay turns on when being limited by high limit.

In Manual operation, the relay turns on while the or key is pressed.
Output limiter does not work.
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.

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