About this item

  • The module uses genuine quality relay, normally open interfaces , Maximum load: AC 250V/10A, DC 30V/10A.
  • The Module can be set by jumper high or low trigger.
  • 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.
  • The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient.
