Connecting the Unit to External Devices
Communication Terminal Block
You can connect external devices such as a PC or PLC to the communication terminal block of
DL-RS1A via the communication cables.
■ Terminal connection
* Recommended communication cable
KPEV-SP(1P) wire with balanced type twisted shield (strand wire)
Nominal cross-section area 0.16mm
2 (AWG25) min.
A terminal cover is attached to the terminal block.
The terminal cover must be placed over the terminal block when you finish connecting the cables.
The terminals for SG (Nos. 1, 4, and 5) are used in common with the blue wire of the sensor amplifier
main unit.
● Crimp-type terminal
Use the Y or round terminal for wiring to the I/O terminal.
Use the Y or round terminal with the following dimensions.

Terminal No. Terminal Description
1 SG
Connects to the shielded wire of the communication cable.
The terminals for SG (Nos. 1, 4, and 5) are internally short-circuited.
2 RD (input) Connects to the SD terminal of an external device via a communication cable.
3 SD (output) Connects to the RD terminal of an external device via a communication cable.
4 SG The terminals for SG (Nos. 1, 4, and 5) are internally short-circuited.
5 SG The terminals for SG (Nos. 1, 4, and 5) are internally short-circuited.
6 DRQ (input)
When there is a short-circuit between DRQ and SG, the sensor amplifier data is
transmitted even without a command from the external device.

Connecting the Unit to External Devices
■ Connection wiring
Refer to the connection wiring diagram shown below when connecting DL-RS1A to an external
device such as a PC.
• The length of the communication cable must not exceed 15 m.
• Connect the shield wire of the communication cable to the SG terminal of the external device.
• Make sure that the shield wire does not touch other signal wires or the other terminals on
the terminal block.
■ Optional cable
An optional cable shown below is used to connect to an external device such as a PC that has
a D-sub 9-pin I/O connector.
Part number: OP-81283
Pin layout for D-sub 9-pin connector
*1 Pin numbers 4 and 6 are connected inside the connector.
*2 Pin numbers 7 and 8 are connected inside the connector.
*3 Two cables (black and black/white) are connected to the pin number 5.
