NOTICE:
Before mounting the PI/O module, check to make sure that the connected signal matches
its rating.
If a PI/O module is mounted and an erroneous signal is connected, the PI/O module or external
sensor may got damage.
The terminal block (TB1, TB2) external power supply terminals are connected internally in the
SDI01 and SDO01 modules. When it is necessary to wire between terminal units, use only TB1
terminals or TB2 terminals for all units (do not mix TB1 and TB2 among units).
If the internal path from TB1 to TB2 is used for the jumper wiring to other terminals, it may
happens that the current capacity is inadequate and the pattern is burned.
When branching the external power supply connected to pins 17 and 18 of the terminal block
(TB1, TB2) from pins 19 and 20, make sure that the maximum power-on current is within 2 A.
Otherwise, the current may run short thus resulting in burning of the pattern.
The PI/O module ground is connected to the FG terminal internally. Always ground the
FG terminal.
Otherwise parts will be damaged or system will be malfunction.
Do not connect an external signal line or a power supply line to an open terminal.
Doing so may cause parts to be damaged or malfunction.
