1-6-1 Incremental Encoder Input Units
Item Description
Number of channels The number of encoder input channels of the Unit.
Number of external
inputs
The number of external inputs of the Unit.
Maximum response
frequency

*2. When you use the 5-V power supply for an encoder, be sure to include that current too. Refer to the NX-series Position
Interface Units User's Manual (Cat. No. W524-E1-04 or later) for information on how to convert a 5-V power supply current
consumption to a 24-V power supply current consumption.
