•
Locate the power input rating marked on the product and
confirm its operational range as indicated below:
DC Power supply
: Rated voltage 24V DC
24V DC ± 10%, approx. 12W
(@ internal power max. current 1.6 A)
Excitation supply (excitation for I/O module)
:
24V DC ± 10%, operational current 7A
(From power supply (exitation supply) connector, via con-
nector for internal bus, supplied to each I/O module. Pow-
er output current consumption must be under operational
current.)
■
GENERAL PRECAUTIONS
•
Before you remove the unit or mount it, turn off the power
supply for safety.
■
ENVIRONMENT
•
Indoor use.
•
When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
•
Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
•

cable, high frequency line, etc.).
•
Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
•
Use a ferrite core close to the unit for communication line.
Turn the cable twice (1 round) as figure below.
■
ABOUT SD CARDS
•
Do NOT turn off the power of DL8 during writing data.
Insert or eject SD card according to the specified proce-
dure.
•
Confirm the front and back side of the SD card.
■
AND ....
•
The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.
INSTALLATION
Connection between DL8 series modules is done with the
connector of each module. Therefore, a base is not neces-
sary. Since the connector between modules supplies power
and transfers internal communication data, do NOT change
modules during power supplied.
Hook
DIN Rail Adaptor
■
HOW TO MOUNT THE MODULE ON DIN RAIL
• Web-Enabled RTU Modules
Position the upper hook at the rear on the DIN rail and push in the lower.
When removing the module, push down the DIN rail adaptor utilizing a
minus screwdriver and pull.
