3.4.3  High Speed Input

PLCs do not commonly use 5 volt logic. Signal levels as high as 24 volts may be connected to the 
STEP and DIR inputs if external dropping resistors are added as shown below:

 ▪ For 12 volt logic, add 820 ohm, 1/4 watt resistors
 ▪ For 24 volt logic, use 2200 ohm, 1/4 watt resistors

WARNING: The maximum voltage that can be applied directly to a high speed input termi-

nal is 5 volts. Never apply high voltage AC to an input terminal.
