FAQ for CP1W-8ET
When should I use 8-point vs larger units?
8ET: when you need few additional outputs. Cost-effective for small expansion. For 10+ outputs, larger units (20, 32, 40-point) more cost-effective per point.
What's the power consumption?
50mA at 5VDC (lowest among output units). Ideal when power budget is limited. External: 7mA per output when ON.
Can I use this for high-speed output?
Standard transistor output: 0.5ms response (approximately 1kHz). For high-speed pulse output, use CPU built-in pulse outputs.
Do I need external fuse?
Yes, external fusing recommended. Use 0.5A fast-blow fuse per output or per common group.
