Connecting the Unit to Sensor Amplifiers
Connecting the Unit to Sensor Amplifiers
You use DL-RS1A by connecting it to sensor amplifiers. The connection method varies according to
the mounting type of the sensor amplifiers.
Before connecting DL-RS1A, you must install the main unit and expansion units of the sensor
amplifiers. For installation method, see the operating instructions for the SK-1000 Series.
„ Available sensor amplifiers
Make sure that the sensor amplifiers are turned off before connecting the RS-
232C communication unit DL-RS1A to them. Connecting the unit while the
sensor amplifiers are turned on may damage the unit.

Connecting the Unit to Sensor Amplifiers
„ Connecting the DL-RS1A to DIN rail mount sensor amplifiers
1
Remove the expansion protective cover from the sensor amplifier that you want to connect to
the DL-RS1A.
2 Mount the DL-RS1A on the DIN rail and connect it to the sensor amplifier.
Make sure there is no space between the unit and the sensor amplifier.
3
Mount the end units (OP-26751, two units included) on either side of the sensor amplifier and
DL-RS1A unit and tighten the two screws on the top of each end unit.
(You can mount the end units in the same way you mount DL-RS1A.)

Connector
Check that the sensor amplifier connector (for DIN
rail mounting) located on the side of DL-RS1A is
not installed at an angle as shown in the
illustration to the right. Connecting the unit with
its connector installed at an angle to a sensor
amplifier may damage the unit.

Make sure you firmly insert DL-RS1A all the way into the sensor amplifier.
Turning the power on when the unit is not inserted straight or firmly connected
may damage the unit.
