Connecting to an External Device
 How to connect
To connect BCD Output Unit DL-RB1A to an external device, use the
connector (MIL connector, female, 34-pin) shown below.
 Pin arrangement of I/O connector
*1 Be sure to load the BCD output (Pin No. 6 to 30) when the strobe
output (Pin No. 31) becomes ON. Refer to the "BCD Output Unit
DL-RB1A User's Manual" for more details about the strobe output.
*2 Alarm output will be turned OFF when the alarm is generated.
(ON in normal condition)
 I/O circuit diagram
 Input circuit diagram (Pin No. 1 to 5)
* Pin No. 33 and 34 are common to the 0V blue wire on the main sensor amplifier.
 Output circuit (Pin No. 6 to 32)
* Pin No. 33 and 34 are common to the 0V blue wire on the main sensor amplifier.
Output Settings
Use the advanced setting switch for output settings.
• After changing the
settings, be sure to
cycle power.
• After setting, reattach
the included switch
protection sticker.

Setting enabled only for BCD output (Pin No. 6 to
29) and BCD polarity code output (Pin No. 30).
* Settings before shipment.
Negative logic: Bit of an input device (external device
including PLC) will be 1 when the BCD
output (Pin No. 6 to 30) is ON.
Positive logic: Bit of an input device (external device
including PLC) will be 1 when the BCD
output (Pin No. 6 to 30) is OFF.
