FAQ for NX-OD4121

What's the output current?
0.5A per point. For higher current loads, use output to control external relay/contactor.
What's the response time?
0.5ms. Suitable for most switching applications.
Do I need external fuse?
Yes, external fusing recommended. Use 0.5-1A fast-blow fuse per output.
Can I use this for high-speed output?
0.5ms response (approximately 1kHz). For high-speed pulse output, use dedicated position control unit.
