 Mounting on a DIN rail
1
Fit the tab of the lower part of the main unit to the 
DIN rail. While inserting the main unit in the 
direction of arrow 1, push the body in the direction 
of arrow 2.
2 To detach the main unit, while pushing the 
main unit in the direction of arrow 1, pull the 
body in the direction of arrow 3.
 How to connect to the sensor amplifier
The DeviceNet Compatible Network Unit DL-DN1 is used by connecting it to a sensor 
amplifier. The connection method varies according to the mounting type of the sensor 
amplifier to connect to.
z Connecting to a DIN rail mounting type sensor amplifier.
1 Detach the expansion protective cover of the sensor amplifier to which the 
communication unit is to be connected.
2 Mount the DeviceNet Compatible Network Unit DL-DN1 on the DIN rail and 
connect to the sensor amplifier.
Push and fix the DeviceNet Compatible Network Unit DL-DN1 to make sure there is no 
space between the output unit and the sensor amplifier.
Item Description
(1) Address setting switch Sets the DeviceNet node address of the DL-DN1.
x10 : Ten's digit
x1 : One's digit
Setting range : 00 to 63
Default value : 63
When setting the node address of the DL-DN1 from the 
DeviceNet master unit, set it in the range of 64 to 99.
The DL-DN1 turns into the PGM.
(2) Operating mode setting 
switch
Sets the operating mode of the DL-DN1 in the DeviceNet.
The data that can be handled in I/O communication varies 
with each operating mode.
Basic mode
Use switch bits 1 and 2 to configure the basic mode.
Default value : 3-output mode
• The content of output depends on the sensor amplifiers to 
be connected.
Examples: 3-level judgment output for 3-output mode; 
5-level judgment output for 5-output mode
• The size of occupied memory depends on the number of 
amplifiers to be connected.
Extended mode
Switch bits 3 and 4 can be set to add one of the following 
extended functions to the basic mode.
Default value : No extended mode
The size of occupied memory depends on the number of 
amplifiers to be connected and the setting of the basic mode.

(5) Sensor communication 
indicator
Indicates the status of communication between the DL-DN1 
and sensor amplifiers.

(8) DeviceNet connector Attach the DeviceNet cable to this connector.
When connecting the DeviceNet Compatible Network Unit DL-DN1, 
be sure to check the power of sensor amplifier is OFF before 
performing the operation. Performing the operation when the 
power of sensor amplifier is ON may damage the equipment.
Refer to the Instruction Manual of each sensor amplifier for
details about how to add the sensor amplifier.
Refer to the figure below, and check that the sensor amplifier 
connector (for DIN rail mounting type) on the side of the 
DeviceNet Compatible Network Unit DL-DN1 is not mounted at 
an angle. Connecting to the sensor amplifier with the 
connector diagonally may damage the equipment.
