Frequently Asked Questions
What's the advantage of transistor output vs relay?
Transistor: faster response (0.5ms vs 10ms), longer life (no contacts), silent operation, suitable for PWM. Relay: higher current (5A vs 0.3A), AC/DC switching. Choose based on load type.
Can I use this for high-speed output?
Standard transistor output: 0.5ms response (approximately 1kHz). For high-speed pulse output (stepper control), use CPU built-in pulse outputs or high-speed output unit.
Do I need external fuse?
Unit has internal protection, but external fusing recommended. Use 0.5A fast-blow fuse per output or per common group for load protection.
What's the difference between CP1W-20EDT and CP1W-20EDT1?
20EDT: NPN (sinking) output. 20EDT1: PNP (sourcing) output. Choose based on load wiring requirements and regional standards.
