CE Marking
Keyence Corporation has confirmed that this product complies with the essential
requirements of the applicable EC Directive, based on the following specifications. Be sure
to consider the following specifications when using this product in the Member State of
European Union.
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
incorporated 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.
Characteristics of the DL-PN1
The DL-PN1 is an interface unit, which enables sensors to connect to the PROFINET.
The characteristics of the DL-PN1 are shown below.
• Supports data I/O communication. The device can send and receive data without a
ladder program.
• Supports record data communication. The device can read and write sensor amp
settings and its current status, and issue commands to the sensor amp.
The DL-PN1 can connect to up to 15 units of sensor amplifiers (a single main unit and
multiple 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-PN1
unit.
How many and what types of sensor amplifiers can be connected depends on the sensor
amplifiers or units to be connected. Please inquire for details.
