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