DeviceNet, CC-Link
Universal input (E1-terminal area) can be used
when UT55A/UT52A optional suffix code /U1.
However, DI16 does not exist.
(For Detailed model)
Remote input can be used when UT55A/UT52A optional
suffix code /R1 or /RCH1.
(For Standard model)
Remote 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)
Feedforward input can be used when
UT55A optional suffix code /A2.
(For Standard model)
Feedforward 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.
