Connecting the Unit to Sensor Amplifiers
„ Connecting the unit to panel mount sensor amplifiers
1 Connect DL-RS1A to the sensor amplifiers using the optional expansion cable (OP-35361).
2 Remove the sensor amplifier connector with pliers (for DIN rail mounting when using with panel
mounted sensor amplifiers) from DL-RS1A unit and install the expansion connector cover
supplied with the unit.
• Make sure you securely connect the expansion cable while the unit is turned
off. Turning the power on when the cable is not inserted straight or firmly
connected may damage the unit.
• Removing or inserting the cable while the power is on may damage the unit.

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.

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.
