Wiring for Encoder Following
Using High Speed Inputs with 12-24 Volt Signals
Most PLCs and many sensors don't use 5 volt logic. You can connect signal levels as high as 24
volts to the X1 and X2 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
The maximum voltage that can be applied to an input terminal is 24 volts DC.
Never apply AC voltage to an input terminal.
