Option L5/L5E & L8E Wiring
Option L5/L5E & L8E - 24V AC/DC Interface Board Requirements
Circuits used with these options must be capable of operating with
high = true logic.
DC external circuits in the low state must generate a voltage of no
more than 8V DC. Leakage current must be less than 1.5 mA into a
2.5k ohm load.
AC external circuits in the low state must generate a voltage of no
more than 10V AC. Leakage current must be less than 2.5 mA into a
2.5k ohm load.
Both AC and DC external circuits in the high state must generate a
voltage of +20 to +26 volts and source a current of approximately 10
mA for each input. These options are compatible with the following
Allen-Bradley PLC modules:
• 1771-OB • 1771-OQ16 • 1771-OB16
•1771-OBD •1771-OYL
•1771-OBN •1771-OZL
• 1771-OQ • 1771-OBB
