Safety Precautions
■
General Cautions
•At startup and during operation, be sure to monitor the functions and
performance of the DL-RB1A.
•Provide appropriate safety measures to avoid any damage in the event
that a problem occurs.
•Do not modify the DL-RB1A or use it in any way other than described in
the specifications. The functions and performance of products used or
modified in this way cannot be assured.
•When the DL-RB1A is used in combination with other instruments, its
functions and performance may be degraded, depending on the operating
conditions and surrounding environment. Use the DL-RB1A after fully
studying the effect of combined use with other instruments.
•Do not use the DL-RB1A for the purpose of protecting the human body.
•Do not expose the DL-RB1A and peripheral devices to sudden

rail. While inserting the unit in the direction of
arrow (1), push the body down in the direction of
arrow (2).
2 To detach the unit, lift the unit in the direction of
arrow (3) while pushing it in the direction of arrow
(1).

Mounting bracket: OP-60412
Connecting the Unit to Sensor Amplifiers
When connecting DL-RB1A to the sensor amplifiers, the connection method varies according to the
mounting type of the sensor amplifiers. Before connecting DL-RB1A, you must install any necessary
expansion units to the main unit of the sensor amplifier.
For information on installing the sensor amplifiers, refer to the user's manual supplied with the sensor amplifiers.
Caution
10
Make sure that the sensor amplifiers are turned off before connecting the
BCD output unit DL-RB1A to them. Connecting the unit while the sensor
amplifiers are turned on may damage the unit.

Mounting and Connecting the DL-RB1A
• DL-RB1A does not output decimal points. If there is a decimal point in the sensor amplifier
data, it will be dropped.
[Ex.] When the GT2 Series is connected, the detection data "+12.3456"
is output to the DL-RB1A as "+123456".
• The number of digits sent out of the BCD output cannot be changed. (This does not affect
the number of digits displayed on the sensor amplifier.)
• The GT2 Series sensor amplifier can display up to 7 digits, but DL-RB1A can only output
up to 6 digits.
Pin No. 31: Strobe output
Strobe output is turned on when data can be read from the external device.
When the strobe output is turned off, the BCD output cannot be verified.
Pin No. 32: Alarm output
Alarm output is turned on normally. It is turned off when an alarm occurs.
When an alarm occurs, "+EEEEEE" is output as the BCD data and polarity code.
• The time after the power is turned on but before the first BCD output is confirmed
• When updating the BCD output, if the selected ID number for the sensor amplifier does not exist
• When updating the BCD output, if there is an error with the selected ID number for the sensor
amplifier
• When there is overcurrent error on one of the outputs (Pin Nos. 6 to 32)
• Until the initialization is completed if the main unit (ID: 00) is initialized when it is connected to the
GT2-100N/100P.
* For more information on errors, refer to the User's Manual of each sensor amplifier.

Precautions when wiring (OP-23139 and OP-42224)
Carefully follow the precautions below when performing wiring.
• Use a single shielded cable.
Mounting and Connecting the DL-RB1A
• Use the following type of compliant cable:
Cable size: AWG24 to 22 (stranded)
Cross-section: 0.2 to 0.3 mm
Cable sheath diameter: 1.5 to 1.1
• Cut the end of the cable straight across.
• After performing the wiring, check that the cable is securely held in the clamp and that it is inserted
firmly.
• Cut the cable clearly so that no loose threads remain. (The sheath does not need to be removed.)
• Use the thin cable contacts OP-30594 (200 pieces included) for AWG28 to 26.
(Use this together with OP-23139 or OP-42224.)
Cable size: AWG28 to 26
Cross-section: 0.08 to 0.14 mm
Cable sheath diameter: 1.3 to 1.1

Note
Operation Modes
There are three types of operations modes for DL-RB1A: OUT mode, OR mode, and TIMER mode.
Different ON/OFF combinations of the advanced setting switches can be used to toggle between the
operation modes. For more details, see to Advanced setting switches on (page 7) .
OUT mode
This is an all-purpose mode that uses BCD output to output data from the sensor amplifier with the
selected ID No. when the DRQ input from the external device is switched.
Set the external device so that there is at least 2 ms before turning DRQ input on and after
turning DRQ input off.
