Description
-
The module uses a genuine quality relay, normally open interfaces , Maximum load: AC 250V/10A, DC 30V/10A.
-
Using SMD optocoupler isolation, strong driving capability, stable performance; trigger current 5mA.
-
Fault-tolerant design, even if the control line is broken, the relay will not move.
-
All interfaces are available through a direct connection terminal leads.
-
The Module can be set by a jumper to a high or low trigger.
