1. DC power supply
2. Emergency stop
3. Circuit protection fuse
4. Flywheel diode + inductive load
5. Manually exclusive output *1
*1: Transistor outputs use internal zener diode (39V) as protection circuitry. When driving the
inductive load with transistor output, a reverse-current protection diode can be installed in
parallel with the load if necessary.
The reverse-current protection diode needs to satisfy the following specifications.
- The diode is rated for maximum reverse voltage of 5 to 10 times the load voltage.
- The forward current is more than the load current.
