Sensor burnout occurs when PV or RSP input burnout occurs.
However, burnout is not detected if input is not connected.
Control computation
RSP terminal input (ON)/PV terminal input (OFF) switch
(Current when retransmission output)
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.
No function
is assigned
to DI3.

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