Necessary for Loop control with PV auto-selector for 3 inputs or 4 inputs
Can be used when UT55A suffix code: Type 2 = 7 and
not in Loop control with PV auto-selector for 4 inputs.
However, use the LL50A to set remote input.
Sensor burnout occurs when PV, RSP, AIN2, or AIN4 input burnout occurs.
However, burnout is not detected if input is not conncted.
* After the control output terminal is specified by the parameter OT,
other current output terminals can be used as retransmission output.

optional suffix code /A4 or /AC4.
(For Standard model) When UT55A
suffix code: Type 2 = 7.
(For Detailed model)
DI16 is equipped when UT55A optional suffix code /R1.
DI26 is equipped when UT55A optional suffix code /A2.
DI46 is equipped when UT55A optional suffix code /A4 or
/AC4.
(For Standard model)
DI16 is equipped when UT55A
suffix code: Type 2 = 1, 2, 4, 5, or 7.
(For Standard model) UT55A suffix code: Type 2 = 1, 2, 4, 5, or 7 is necessary.
Universal input (E1-terminal area) can be used when UT55A
optional suffix code /U1. However, DI16 does not exist.
For the model with optional suffix code /DR: Refer to the function
block diagram of Loop control with PV auto-selector (2 inputs).
