9.5.4 An external wiring example for the extension power supply unit (sink input [-common])
This example shows a sink input wiring (-common),including the extension power supply unit.When adding an
input extension block,check the signal name on the terminal block since the sink/source type and sink type
differ from each ther.
AC power supply of
100 to 240V
*1 Connect the AC power supply to the L and N terminals (in any case of 100V
AC system and 200V AC system).
Make sure that the power is turned ON at the same time in the main unit
and extension power supply units or earlier in extension power supply units
than the main unit.
As for details, see "WIRING PRECAUTIONS" at "Safety Precautions" field.
*2 Connect the 24V terminal of the main unit to the S/S terminal of the input
extension block.
*3 In case of the sink input type, the S/S terminal is used as the 24+ terminal.
*4 Some special function units/blocks or special adapters do not have a power
supply terminal. When using an external power supply, turn it ON at the same
time with the main unit or earlier than the main unit.
When turning OFF the power, confirm the
safety of the system, and then turn OFF the
power of the PLC (including special
extension equipment) at the same time.
*5 Some special function units/blocks do not
have a power supply terminals.
When using an external power supply, turn it
ON at the same time with the extension
power supply unit or earlier than the
extension power supply unit.
When turning OFF the power, confirm the
safety of the system, and then turn OFF the
power of the PLC (including special
