6-2-2
External Analog Setting Input
When a voltage of 0 to 10 V is applied to the CP1H CPU Unit's external ana-
log setting input terminal, the voltage is converted from analog to digital and
the PV in A643 can be changed to any value within a range of 0 to 256 (0000
to 0100 hex).
External Analog Setting
Input Wiring
Use the 1-m lead wire (included) for wiring to the external analog setting input
connector on the CP1H CPU Unit.
Relationship between
Input Voltage and PV in
A643
The maximum input voltage is 11 VDC. Do not apply a voltage greater than
that.
Application Example
Setting the value for timer T101 in A643 makes it possible to use T101 as a
variable timer with a range of 0 to 25.6 s (0 to 256). A change in the set value
is reflected with the next scan.
Note
External analog setting input values may vary with changes in the ambient
temperature. Do not use the external analog setting input for applications that
require highly precise set values.
