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

2) In the case of source wiring
Use the sink/source common input, source only output type main unit, a sink/source common input type
input extension block and a transistor output (source only output) type output extension block. The wiring
example is the [FX
