6-5-4 NX-EC0142
This section provides diagrams of the terminal block arrangement and internal power supply wiring of
the NX-EC0142. It also provides a wiring example.
Two 12-terminal terminal blocks are used.
Note 1. The sensor power supply output (24 V and 0 V) is provided power from the I/O power supply connected
to the Communications Coupler Unit or an Additional I/O Power Supply Unit.
2. The power supply output for encoders (5 V and 0 V) is converted from the 24-VDC I/O power supply to 5
VDC inside the Incremental Encoder Input Unit.
