The module uses genuine quality relay, normally open interfaces. Using SMD optocoupler isolation, it has driving ability, stable performance. The module can be set high or low by a jumper setting trigger.
It has a fault-tolerant design, if the control line is broken, the relay will not operate. The power indicator (green), the relay status indicator (red). All interfaces are available through a direct connection terminal leads, which is very convenient.
