Product description
12V Optocoupler Relay Module With 1 Channel High/Low Level Trigger Expansion Board For Your Projects
The module uses premium quality relay, normally open interfaces, maximum load: AC 250V/10A, DC 30V/10A.
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 operate.
Power indicator (green), relay status indicator (red).
User-friendly interface design, all interfaces can be directly connected through the terminal block, very convenient.
The module can be adjusted to high level signal trigger or low level signal trigger.
Operating Voltage: DC 12V
Maximum Load: AC 250V/10A, DC 30V/10A
1. DC+: Connected to the positive pole of the power supply (12V)
2. DC-: Connected to the negative pole of the power supply
3. IN: Signal trigger input
1. NO: Relay normally open interface, suspended before the relay pulls in, shorted with COM after the relay pulls in
2. COM: Relay common interface
