(2) When the extension base A1S52B(S1), A1S55B(S1), A58B(S1) or A52B, A55B, A58B are used, the 5VDC
power is supplied from the power supply module of the main base unit. Before use, refer to Section 6.1.3
Notes
and examine if it can be used.
(3) Limit the length of extension cable to 6m (236inch) or shorter.
(4) When using the extension cable, do not tie it with the main circuit cables, which has high voltage, large
current, or install them close to each other.
(1) Assign I/O numbers to the main base unit first, then to the extension base unit.
(2) Assign I/O numbers as if both main base unit and extension base unit have 8 slots each. When the
A1S32B/A1S33B/A1S35B for 2/3/5 slots are used as the main base unit, add 6/5/3 slots (96 points/80
points/48 points) and assign the extension base unit I/O numbers.
