DL-CL1 Overview
This unit operates as a remote device station (Ver. 1.1 and 2 switchable) of a CC-Link
system. Using CC-Link communications, the sensor amplifiers and other units con-
nected to the DL-CL1 can transmit their ON/OFF control signals and current values as
communication data to PLC or other equipment.
The DL-CL1 supports cyclic transfer and extended cyclic transfer, enabling data com-
munication without the need of a ladder program. In addition, remote input/output sig-
nals can be used as handshake signals to read/write settings of sensor amplifiers and
to execute motion commands on the sensor amplifiers.

Number of Connectable Sensor Amplifiers
* Cannot be connected to a panel mounting type.
The DL-CL1 can connect multiple 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 the single
DL-CL1 unit.
How many and what different types of sensor amplifiers can be connected depends
on the sensor amplifiers or units to be connected. Please inquire for details.
