DL-PD1
The DL-PD1 is an interface unit, which enables sensor amplifiers or input units to
connect to the PROFIBUS DP. The characteristics of the DL-PD1 are shown below.
Slave unit of the PROFIBUS DP-V1
Before Using
The following features are achieved by connecting the sensor amplifiers, which
are suitable for each application, in the form of a module.
• Reading out the output of the sensor amplifier.
• Reading out the comparator value (the measurement value) of the sensor
amplifier.
• Changing the configuration of the sensor amplifier.
Two selectable operational modes
• Monitor Mode: Input size - MAX 107 bytes, Output size - MAX 16 bytes
• I/O Mode: Input size - 10 bytes, Output size - 10 bytes
Corresponding to the communication speed of 9.6 Kbits/s to 12 Mbits/s
System configuration example
Additional sensor amplifiers corresponding to the D-bus can be connected to the DLPD1. ("D-bus" is the name of KEYENCE's wiring-saving system for sensor amplifiers.)
Any sensor amplifiers corresponding to the D-bus allow different models and up to 15
units of sensor amplifiers to be connected simultaneously.
Connectable quantity depends on the sensor amplifier which is connected to.

system for sensor amplifiers.
Different types of sensor amplifiers with D-bus support can be connected to a single DLPD1 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.

Sensor amplifier
Expansion connector
This section provides the procedures for installing the DL-PD1 and connecting to sensor
amplifiers.
The DL-PD1 can be connected with the sensor amplifiers which support D-bus. ("D-bus"
is the name of KEYENCE's wiring-saving system for sensor amplifiers.) How many
sensor amplifiers can be connected depends on the sensor amplifiers to be connected.
For specific numbers of connections, refer to the manual of each sensor amplifier.
Installation and Connection to a Sensor Amplifier
Connection and Configuration
Installation and Connection to Sensor Amplifiers
Turn off the power before connecting the DL-PD1 and sensor amplifier.
1 Align the claw on the bottom of the DL-PD1 with the DIN rail. While pushing
the amplifier in the direction of arrow (1), press down in the direction of arrow
(2).
To remove the DL-PD1, raise the amplifier in the direction of arrow (3) while
pushing the amplifier in the direction of arrow (1).
2 Repeat step 1 to install additional sensor amplifiers or input units on the DIN
rail and connect them to the DL-PD1.
If the sensor amplifier connector has an expansion protective cover, remove the
cover before connecting the amplifier.

NOTICE
Make sure that the sensor amplifier connector (for DIN rail mounting
type) is not askew on the side face of the DL-PD1, as shown below. If
the connector is askew, the DL-PD1 may become damaged when
connected to the sensor amplifier.

3 Mount the end units (OP-26751: a two-unit set shipped with the DL-PD1) on
both sides of the DL-PD1 and the sensor amplifier. Then, fix the end units
with the screws on the top of each end unit. (Tightening torque: 0.6 N•m or
less)
Mount the end units in the same way as the DL-PD1.
Connection and Configuration
Press the DL-PD1 into full engagement with the sensor amplifier. If
the DL-PD1 is not correctly connected, it may be damaged when the
power is turned on.

Connection and Configuration
• Turn off the power and connect the expansion cable securely. If the
cable is not correctly connected, the DL-PD1 may be damaged
when the power is turned on.
• Do not attach or detach the cable with the power on, as this may
damage the DL-PD1.
2 Remove the sensor amplifier connector (for DIN rail mounting type) from the
DL-PD1, using pliers. In its place, attach the expansion connector sticker
supplied with the DL-PD1.

Setting the Station Address
Set the station address of the DL-PD1 with the rotary switch at the top of the DL-PD1.
The station address set here must be the same as the one set through the configuration
software of the PROFIBUS DP.
Connection and Configuration
• The station address of the DL-PD1 cannot be set to 00, 100, or more.
• Set the station address before the DL-PD1 is powered on. When the
station address is changed during operations of the DL-PD1, such
change is reflected after power has been restored to the DL-PD1.
• The station address setting (Set_Slave_Adress) via PROFIBUS DP is
not supported.
