FAQ for NX-OD5121-1
What's the difference between NX-OD5121-1 and NX-OD5121-5?
NX-OD5121-1: 16 points. NX-OD5121-5: 32 points. Same electrical specs. Choose based on I/O density needs.
Can I parallel outputs for higher current?
Yes, parallel multiple outputs from same common for up to 2A combined. Ensure all outputs switch simultaneously.
Do I need external fuse?
Unit has internal short-circuit protection, but external fusing recommended for load protection. Use 0.5-1A fast-blow fuse per output.
Is this output suitable for stepper motor control?
No, OD5121 is for on/off switching. For stepper motor pulse/direction, use NX-PG pulse output unit or controller built-in pulse outputs.
