„ Noise Protection
If this product is installed in a location near a noise source, e.g, power source or high-voltage
line, it may malfunction or fail. Use protective measures, such as using a noise filter or running
the cables separately.
„ About the Power Supply
• Noise superimposed on the power supply may result in malfunction. Use a stabilized DC
power supply configured with an isolation transformer.
• When using a commercially available switching regulator, be sure to ground the frame ground
terminal.
„ UL Certification

z EMC Directive
EMI : EN55011, Class A
EMS : EN61000-6-2
• Use a STP (shielded twisted pair) cable for connection to the network.
These specifications do not give any guarantee that the end-product with this product incor-
porated complies with the essential requirements of EMC Directive. The manufacturer of
the end-product is solely responsible for the compliance on the end-product itself according
to EMC Directive.
The DL-EP1 is an EtherNet/IP compatible adaptor which can read and write the data from the
connected sensor amplifier from a PLC (programmable controller) or PC (personal computer).
• The DL-EP1 supports cyclic communication. Data can be exchanged without a ladder pro-
gram.
• The DL-EP1 also supports UCMM and Class 3 (explicit message communication). The sen-
sor amplifier settings and status can be read and written at a random timing, and motion com-
mands can be issued to the sensor amplifier.
The DL-EP1 can connect a maximum of 15 sensor amplifiers (main units and expansion units)
which support D-bus. ("D-bus" is the name of KEYENCE's wiring-saving system for sensor
amplifiers.)
Different types of sensor amplifiers with D-bus support can be connected to a single DL-EP1
unit.
The number of connectable units, and a mixed environment of different models, depend on the
particular sensor amplifiers or units. Refer to the “DL-EP1 User’s Manual”.
Before using the DL-EP1, make sure that the following equipment and accessories are included
in the package.
We have thoroughly inspected the package contents before shipment. However, in the event of
defective or broken items, contact your nearest KEYENCE office.
