■Output current
Maximum load differs for each module. For specifications of each module, refer to the following.
For output specifications of the CPU module, refer to Page 31 Output Specifications.
For output specifications of the I/O modules, refer to Page 152 Output specifications.
For output specifications of the terminal modules, refer to Page 170 Output specifications.
When driving a semiconductor device, carefully check the input voltage characteristics of the device.
■Open circuit leakage current
0.1 mA or less
Wiring precautions
■Protection circuit for load short-circuiting
A short-circuit at a load connected to an output terminal could cause burnout at the output device or the PCB.
To prevent this, a protection fuse should be inserted at the output. Use a load power supply capacity that is at least 2 times
larger than the load current.

■Contact protection circuit for inductive loads
When an inductive load is connected, connect a diode (for commutation) in parallel with the load as necessary.
The diode (for commutation) must comply with the following specifications.
Standard
Reverse voltage
Forward current
Inductive load
Fuse
■Interlock
For loads such as forward/reverse contactors, etc., where a hazardous condition could result if switched ON simultaneously,
an external interlock should be provided for interlocking along with an interlock in the PLC program, as shown below.
