1 Channel 5V Relay Module High/Low Trigger

Description

• Module Description:
  1 – Module uses genuine quality relay, normally open interfaces Maximum load: AC 250V / 10A, DC 30V / 10A.
  2 – SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA.
  3 – Module voltage 5V
  4 – Module can be set to trigger high or low with jumpers.
  5 – Fault-tolerant design, even if the control line is broken, the relay will not operate.
  6 – Power indicator (green), relay state indicator (red)
  7 – user-friendly interface design, all interfaces are available through the wiring terminal direct connection leads,       very convenient
  8 – Module size: 50mm x 26mm x 18.5mm (L x W x H)
  9 – Four mounting bolts holes, hole 3.1mm, 44.5mm x 20.5mm pitch
• Two, module interface:
  1 – DC +: positive power supply (
  2 – DC-: negative one
  3 – IN: can be high- or low-level control relay
• Relay outputs:
  1 – NO: normally open relay interfaces, relay before hanging, pull back with COM
  2 – COM: Relay Common Interface
  3 – NC: normally closed relay interfaces, relay before with COM, pull vacant post
• High and low end of the trigger selection:
  1 – Jumper LOW LOW trigger short-circuited.
  2 – When the trigger is high with high short jumper.
