■
Resistance load
For maximum load specifications of resistance load, refer to the following.
Handling of relay output
■
Output terminal
For the relay type, one common terminal is used for 4 or 8 output points (3 or 4 output points for the FX5UJ).
The common terminal blocks can drive loads of different circuit voltage systems (for example, 100VAC and 24VDC).
■
External power supply
Use an external power supply of 30VDC or less or 240VAC or less (250VAC or less when the module does not comply with
CE, UL, cUL standards) for loads.
■
Circuit insulation
The programmable controller 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 supplied to the output relay coil, the LED turns on 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 approximately10ms.
■
Output current
At a circuit voltage of 240VAC or less (250VAC or less when the module does not comply with CE, UL, cUL standards), a
resistance load of 2A per point or an inductive load of 80VA or less (100VAC or 200VAC) can be driven.
For the life of the contact for switching an inductive load, refer to
When an inductive load is switched, connect a diode (for commutation) or a surge absorber in parallel with this load.
■
Open circuit leakage current
There is no leakage current when the outputs are off.
