Four hole mounting bolts, 3.1mm diameter
Color: As shown
Description of the module:
1. The module uses authentic quality relay, normally open interfaces
Maximum load: AC 250V / 10A, DC 30V / 10A;
2. Use SMD isolation optocoupler, ability to drive, stable performance.Trip 5mA current.
3. The operating voltage of the module 5V;
4. The module can be high or low by a trigger of the jumper setting.
5. The fault-tolerant design, even if the command line is case sensitive, the relay won't work;
6. The power indicator (green), the flag of the State of the relay (red)
1. DC: positive supply (VCC)
2. DC: power negative (GND)
3. IN: control relay may be high or low level
1. NO: normally open relay interface
2. COM: Common interface relays
3. NC: normally closed relay interface
High and low level triggering options:
