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 information on installing the sensor amplifiers, refer to the user's manual supplied with
the sensor amplifiers.

Available sensor amplifiers

*1

If even one GT-70A Series unit is included, then the maximum connectable number becomes 10
units (main: 1, expansion: 9).

*2

For the large display type sensor amplifier, up to 11 expansion unit sensor heads can be added
to one amplifier by connecting the head expansion board to the main unit.

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.

NOTICE

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.
