5V 12V 24V Relay Module with Optocoupler Relay Output 1 2 4 6 8 16Way for Automation Equipment Control WXRKDZ(12v 2 Channel Relay)

RelaysCircuit 50mm * 26mm * 18mmProduct size : 26mm*50mm2-way dimension drawing 50 * 41 * 17.5MM4-way dimension drawing 75 * 51 * 16.5 MM8-way dimension drawing 142 * 52 * 18 MMI. module description:1. The module adopts genuine high-quality relay, and the maximum load of normally open interface: AC 250V / 10A, DC 30V / 10A;2. Chip mounted optocoupler isolation is adopted, with strong driving ability and stable performance; Trigger current 5mA;3. The working voltage of the module is 5v12v2v4. The module can be triggered by setting high level or low level through jumper;5. Fault tolerant design, even if the control line is broken, the relay will not act;6. Power indicator (green), relay status indicator (red)7. The interface design is user-friendly, and all interfaces can be led out directly through the wiring terminal, which is very convenient8. There are 4 fixing bolt holes with a diameter of 3.1mmTwo module interface:1. DC +: connected to the positive pole of power supply (voltage according to relay requirements)2. DC -: connected to negative pole of power supply3. In: high or low level control relay can be appliedRelay output:1. No: normally open interface of relay. The relay is suspended before being pulled in, and is short circuited with com after being pulled in2. COM: relay common interface3. NC: normally closed interface of relay. The relay is short circuited with com before being pulled in and suspended after being pulled inHigh and low level trigger selection terminal:1. When the jumper is short circuited with low, it is triggered at low level;2. When the jumper is short circuited with high, it is triggered by high level.
