Equipped as standard
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.
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.
Sensor burnout occurs when PV or RSP input burnout occurs.
However, burnout is not detected if input is not conncted.
In Manual operation, the relay turns on while the
or key is pressed. Output limiter does not work.

Universal input (E1-terminal area) can be used
when UT55A/UT52A optional suffix code /U1.
However, DI16 does not exist.
(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.
