[Design Precautions]
!
DANGER
Configure a safety circuit so that the safety of the overall system is maintained even when an
external power error of PLC error occurs.
Accident may occur due to output error or malfunctioning.
(1) The status of analog output changes depending on the setting of various functions that
control the analog output. Take sufficient caution when setting for those functions.
For details of analog output status, refer to Section 3.4.1 "
Combinations of functions in each
part
"
(2) Normal output may not be obtained due to malfunctions of output elements or the internal
circuits.
Configure a circuit to monitor signals which may lead to a serious accident.
!
CAUTION
Do not bunch the control wires or communication cables with the main circuit or power wires, or
install them close to each other.
They should be installed 100mm (3.9inch) or more from each other.
Not doing so could result in noise that would cause erroneous operation.
•
At power ON/OFF, voltage or current may instantaneously be output from the output terminal of
this module.
In such case, wait until the analog output becomes stable to start controlling the external device.
