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:
