Fixing the I/O module
When fixing the I/O module, tighten all of four screws.
Otherwise, the module will be greatly affected by vibration, causing failure of the module.
When installing the module, tighten screws within the following torque range.
Module mounting screw (M4 screw)
Screw for an FG metal fitting (M3 screw)
• Do not put oil on the screw. Failure to do so may damage the screw.
• Tighten the screw with an applicable screwdriver. Tightening it with an inapplicable screwdriver may
damage the screw.
Wiring the Power Supply
When wiring the power supply, wire the POWER IN terminal and the power supply connector of the I/O module.
Transition wiring of the power supply
When installing multiple I/O modules, the power can be supplied to the modules through transition wiring.
For transition wiring, connect wires between the POWER OUT terminal of the I/O module that will be the power supplier and
the POWER IN terminal of another I/O module that will be a power supply destination.
*1 The largest current flows from the power supplier to the power supply connector of the first I/O module. Make sure that the current does
not exceed the current capacity (8A/pin) of the power supply connector. For a power supply to supply 24VDC, use a power supply (SELV
power supply) that does not exceed 30VAC (effective value), 42.4V (peak value), or 60VDC. Also, use a power supply which is applied
to "limited-energy circuit" defined in IEC61010-1.
(1) Power supply
For transition wiring, check the current consumption of each of wired I/O modules.
For the current consumption of an I/O module, refer to the following.
