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.

(For Detailed model)
Cascade input can be used when UT55A/UT52A optional
suffix code /R1 or /RCH1.
(For Standard model)
Cascade input can be used 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.
(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.
Universal input (E1-terminal area) can be used
when UT55A/UT52A optional suffix code /U1.
However, DI16 does not exist.
