Περιγραφή

  • Maximum load:AC 250V/10A, DC30V/10A
  • SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA
  • The module voltage 5V
  • Each channel module can be set high or low triggered by jumper
  • Fault-tolerant design, even if the control line is broken, the relay will not operate
  • Power indicator (green), 2 relay state indicator (red)
  • Interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient
