Using High Speed Inputs with 12-24 Volt Signals
Most PLCs don’t use 5 volt logic. You can connect signal levels as high as 24 volts to the
STEP and DIR inputs if you add external dropping resistors, 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
terminal is 5 volts. Never apply high voltage AC to an input terminal.
