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 The GT-70A Series, GT2 Series, IG Series, IL Series and IB Series can be connected solely. In
addition, two or more models can be used together.
The maximum connectable numbers for each model are as follows.
• When connecting 1 model only
• When connecting 2 models together
• When connecting 3 or more models together
When using 2 or more models together, the total connection number for each model must be the
maximum connectable number or less for connecting one model only.
(Example) When IB Series and IG Series are used together, sum of the 2 models must be 6 units or
less. In addition, the number of IB Series and IG Series must be 4 or less respectively.
(Connectable)
IB Series 4 units, IG Series 2 units, Total 6 units
(Not connectable) IB Series 5 units, IG Series 1 units, Total 6 units
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
*2 As for the large display type, GT2-100 Series, up to 11 units of the sensor head can be
connected to 1 amplifier by adding the expansion board to the main unit.
GT2-100 Series cannot be used with other models.
■ 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.
