7 Examples of Wiring for Various Uses
7.4 Digital Switch [DSW (FNC 72)/BIN (FNC 19)]
2) In the case of source wiring
Use the sink/source common input, source only output type main unit and a transistor output (source only
output) type output extension block.
The wiring example is the [FX
3UC-32MT/DSS] + output extension block [FX2NC-16EYT-DSS].
3. Input extension block + Output extension block

Example of wiring
1) In the case of sink wiring
Use the sink only input, sink only output type main unit, a sink only input type input extension block and a
transistor output (sink only output) type output extension block.
The wiring example is the [FX
3UC-32MT/D or FX3UC-32MT-LT] + input extension block [FX2NC-16EX] +
output extension block [FX
2NC-16EYT].
