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.

* After the control output terminal is specified by the parameter OT,
other current output terminals can be used as retransmission output.

Sensor burnout occurs when PV or RSP
input burnout occurs.
However, burnout is not detected if input
is not conncted.

Input ladder calculation program (signal goes to the control computation as is when without ladder program). For ladder program, see the LL50A Parameter Setting Software User’s Manual.
Output ladder calculation program (signal goes to the output as is when without ladder program). For ladder program, see the LL50A Parameter Setting Software User’s Manual.
Manual output is prioritized even if
sensor burnout occurs in MAN.

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.
