*1: If an inductive load, such as a relay, is to be connected, a surge protector is required on the load side. Connect a
surge protector or a diode across the load nearby so that the module output terminal voltage will not exceed the
specified operating load voltage range. For details, see Subsection A3.6.5, “Connecting Output Devices.”
*2: The contact operation of the output block of the circuit and the LED display operate independently and thus may be
inconsistent in the event of an error.
*3: For information on the module’s behavior during a CPU failure, see subsection A4.3.3, “Indicating Problem Severity
and Status of Output Module.”
WARNING
Don’t connect DC load and AC load to single module together.
Don’t connect loads from different AC sources to single module together.
In case of using these loads at once, connect to different relay output modules
separately.
Note
The relays in the relay output modules are not of hermetically sealed type.
Dust or corrosive gases in the installation environment adversely affect the service life
of the relays.
Relays that are switched on and off in an atmosphere containing silicone gases from
silicone-based materials may suffer from poor electrical contact due to SiO
2
(silicon
dioxide) formed and deposited on the surfaces of their contacts.
Risks of bad contact due to silicon gases are especially high under load conditions
below 24V DC and 500mA. In such environments, we recommend the use of transistor
output modules or other modules employing semiconductor elements instead.
