Option L5/L5E – 24V AC/DC Interface Board Requirements
Circuits used with Option L5/L5E 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. The L5/L5E option is compatible with these
Allen-Bradley PLC modules:
