FEATURES:
  • 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.
  • The module Operating voltage 5V.
  • The 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.
  • The power indicator (green), the relay status indicator (red).
  • The interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient.
