Connection and Installation Methods
[4] Connecting to the input/output terminals (parallel I/F)
8 input terminals and 9 output terminals are available on the input/output terminal block on the
controller (IV-C35M).
The input terminal block has INPUT terminals X0 to X7 and COM , and the output terminal block has
OUTPUT terminals Y0 to Y7, READY and COM .

The input/output terminals are isolated by photocouplers, to prevent malfunctions due to noise. Use
them within the rated range. The specifications of the input/output ports are listed below.
