About this item
High Quality Module – the relay module uses genuine high-quality relays. The maximum load of the frequently opened interface is: AC 250v/10a, DC 30v/10a.
Adopts SMD Optocoupler Isolation – Use two sets of fully isolated power supply system power, to ensure that the relay in the switch will have an impact on the signal circuit and can be freely switched to high level drive mode or low level drive mode. Trigger Current is 5mA.
“High”, “Low” Level Controllable – With a jumper cap, you can choose a low level control or a high level control, allowing the relay module to adapt to more occasions.
It Has a Fault-Tolerant Design – Even if the control line is broken, the relay won’t actuation.
User-friendly Interface Design – All interfaces can be directly connected through the terminal block, which is very convenient
