Connecting the DL-RB1A to External Devices
Pin Nos. 1 to 4: ID No. selection input
Select the ID number for the sensor amplifier that outputs data by changing the combination of input
signals that are turned on or off. For information about ID numbers, refer to "Sensor Amplifier ID
Number Assignments" (page 24).
*1 The IG Series and IB Series do not use ID No. 04 to 15.
The GT-70A Series does not use ID No. 10 to 14.
The IL Series and SK-1000 Series does not use ID No. 08 to 15.
ID No. 15 outputs the P.V. value for the main unit when using a calculation function other than
reference difference display on the GT2 Series or GT-70A Series. (During this time, ID No. 00
outputs the R.V. value for the main unit.)
For information about the calculation function, refer to the User's Manual of each sensor amplifier.
Pin No. 5: Data request input (DRQ)
Within 2 ms after the DRQ input is turned on, the data from the sensor amplifier with the selected ID
number is updated and output through BCD output. For more information, refer to "Chapter 3:
Advanced Functions" (Page 23).
Pin Nos. 6 to 30: BCD output and BCD data polarity code
Represents a signed six digit figure depending on the combination of outputs that are turned on or
off.
Set the DL-RB1A output logic with the advanced setting switch No. 1. For more information on
advanced setting switches, refer to "Part Names and Functions" (page 6).
The following table shows examples of BCD output (pin Nos. 6 to 30).

* When the output logic is negative logic, the output is turned off for 0 and turned on for 1.
When the output logic is positive logic, the output is turned on for 0 and turned off for 1.
