3.1.1 Characteristics of Input/Output Circuits

The I/O circuits of the FP7 Multi I/O Unit incorporate the following mechanism. Make the
setting of the actual inputs/outputs and the settings on the software be the same.
 Input circuit
A circuit for detecting an input voltage and switching an input impedance is built in. It can be
used with any of 24 V, 12 V and 5 V. The voltage mode is set by the software. The input
current varies according to the input voltage.
 Output circuit
A MOSFET is built in, and it can be used in any of the sink output, source output, push-pull
(negative logic output) and push-pull (positive logic output) modes. The output mode is
selected by the software.

3.1.2 I/O Terminal Layout Diagram

 Terminal layout diagram
The input is allocated to the upper 20 pins (A1 to A10/B1 to B10) of the connector, and the
output is allocated to the lower 20 pins (A11 to A20/B11 to B20).
