Description of KNACRO 4 Channel Optocoupler Isolation Arduino Tools & Equipment

This module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A. Using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA. This module can be high or low by a jumper setting trigger. Fault-tolerant design, even if the control line is broken, the relay will not operate.

Is there a scheme?

High/Low Ratio Confusion. How does level shift actually work? Are combinations possible? The inputs are opto-isolated but connected to a common 24 volt supply.

Pros
  • New
Cons
  • Write Later

Faulty relay on power supply accessory

The product did not work. I ordered 2 relays from the same seller. The first season was delayed and never even delivered. I had to rewind the second relay overnight and it failed and now my project is doomed.

Pros
  • Handsfree
Cons
  • I vaguely remember

Good for low current thin wire applications

Excellent relays with screw terminals for relay connections and I/O contacts. The relay contacts should easily accept 16-18 AWG wire. but don't expect 14 AWG solid or 16 AWG stranded here.

Pros
  • Satisfied so far
Cons
  • Definitely bad product
