Connecting the Unit to External Devices
Sample wiring
*1 Insulate either the black or black/white cable that is not used.
*2 Connect the shield wire to the SG terminal of DL-RS1A. (Shield wire is connected to the
connector casing.)
The green and green/white-striped wires are not connected to any of the connector pins.
„ Input circuit diagram
* The terminals for SG (Nos. 1, 4, and 5) are connected internally with the blue wire of the sensor
amplifier main unit.

Communication Specifications
This section provides the communication specifications of DL-RS1A and describes how to configure the unit.
Communication Specifications
The following table lists the communication specifications for DL-RS1A.
For communication settings, refer to page 2.
Sensor Amplifier ID Number Assignments
When the main sensor amplifier that is connected to DL-RS1A supports expansion units, the main
sensor amplifier ID number "00" is automatically assigned to the main unit and ID numbers "01 to 07"
to the expansion units.
You cannot change the assignment of sensor amplifier ID numbers.
