■Capacitive load
Capacitive loads can generate rush current 20 to 40 times the stationary current. Make sure that the rush current does not
exceed the current corresponding to the maximum specified resistance load.
Capacitive loads such as capacitors may be present in electronic circuit loads including inverters.
■Resistance load
For maximum load specifications of resistance load, refer to the following.
For output specifications of the CPU module, refer to Page 25 Output Specifications.
For output specifications of the I/O modules, refer to Page 173 Output specifications.
For output specifications of the terminal modules, refer to Page 188 Output specifications.
Handling of relay output
■Output terminal
One common terminal is used for 4 or 8 relay output points.
The common terminal blocks can drive loads of different circuit voltage systems (for example,100 V AC and 24 V DC).

■External power supply
Use an external power supply of 30 V DC or less or 240 V AC or less (250 V AC or less when the module does not comply
with CE, UL, cUL standards) for loads.
■Insulation of circuit
The PLC internal circuit and external load circuits are electrically insulated between the output relay coil and contact.
The common terminal blocks are separated from one another.
■Display of operation
When power is applied to the output relay coil, the LED is lit, and the output contact is turned on.
■Response time
The response time of the output relay from when the power is applied to the coil until the output contact is turned on and from
when the coil is shut off until the output contact is turned off is approx. 10 ms.
■Output current
At a circuit voltage of 240 V AC or less (250 V AC or less when the module does not comply with CE, UL, cUL standards), a
resistance load of 2 A per point or an inductive load of 80 VA or less (100 V AC or 200 V AC) can be driven.
For the life of the contact for switching an inductive load, refer to Page 114 Inductive load.
When an inductive load is switched, connect a diode (for commutation) or a surge absorber in parallel with this load.
