Features and Main Functions
Note
CPU Units with Built-
in Analog I/O
Terminals: XA
Note
Settings in the PLC Setup determine whether each input point is to be used
as a normal input, interrupt input, quick-response input, or high-speed
counter. The instruction used to control each output point determines whether
it is used as a normal output, pulse output, or PWM output.
The XA CPU Unit adds analog I/O functionality to the X CPU Unit capabilities.
24 built-in inputs (Functions
can be assigned.) (See note.)
Normal inputs (24)
Interrupt inputs (8)
Quick-response inputs
(8)
4 analog inputs
2 analog outputs
16 built-in outputs (Functions
can be assigned.) (See note.)
Normal outputs (16)
• The CPU Unit has 24 inputs and 16 outputs built in.
• High-speed counters and pulse outputs can be used on four axes with the
CPU Unit alone.
• The CPU Unit has 4 analog voltage/current inputs and 2 analog voltage/
current outputs built in.
• The CP1H can be expanded to a maximum total of 320 I/O points by
using CP-series Expansion I/O Units.
• Using CP-series Expansion Units also allows extra functions (such as
temperature sensor inputs) to be added.
• Installing an Option Board enables RS-232C and RS-422A/485 communi-
cations for connecting to Programmable Terminals, Bar Code Readers,
Inverters, etc.
• Using CJ-series CPU Bus Units enables communications with higher and
lower level devices.
Settings in the PLC Setup determine whether each input point is to be used
as a normal input, interrupt input, quick-response input, or high-speed
counter. The instruction used to control each output point determines whether
it is used as a normal output, pulse output, or PWM output.
