Analog Output Specifications
Note 1:
Total input system transfer time = Sample repetition time + Internal processing time
When using the FC4A-J4CN1, FC4A-J8C1, or FC4A-J8AT1, the total input system transfer time increases in propor tion to the
number of channels used.
Note 2:
The data processed in the analog I/O module can be linear-converted to a value between –32768 and 32767. The
optional range designation, and analog I/O data minimum and maximum values can be selected using data registers allo-
cated to analog I/O modules. See page 4-12.
Note 3:
When an error is detected, a corresponding error code is stored to a data register allocated to analog I/O operating
status. See page 4-6.
Note 4:
The value is measured when a 500V clamp voltage is applied to the power supply and I/O lines.
