2-way 12V relay module series relay module, using chip optocoupler for isolation, stable performance, humanized design, can choose high level or low level signal trigger, only need 5mA. Stable performance, humanized design, you can choose high level or low level signal trigger, only 5mA Current can drive the control capacity of 30A relay suction, the module adopts genuine high-quality power relay, small package photocoupler, large-scale power relay module.; The module adopts genuine high-quality relays, normally
open interface maximum load: AC 250V/10A, DC 30V/10A. The use of chip optocoupler isolation, drive ability, stable performance; trigger current 5mA; Module working voltage 12V; The module can be set through the jumper high level or low level trigger; fault-tolerant design, even if the control line is broken, the relay will not act; power indicator (green), relay status indicator (red).
Module size: 50mm * 41mm * 18.5 mm (L * W * H); Module Interface 1DC+connect to the positive pole of the power supply.
2DC-: connect to the negative pole of the power supply. 3IN11-channel signal trigger terminal, you can set high or low level to control the relay suction. 3IN22-channel signal trigger terminal, you can set high or low level to control the relay suction.; Relay output NO11-channel relay normally open interface, the relay is suspended before it is activated, and is shorted to COM1 after it is activated. COM11-channel relay common interface. NC11-channel relay normally closed interface, shorted to COM1 before the relay is absorbed, and suspended after absorption. NO22-channel relay normally open interface, the relay before the absorption of the vacant, after the absorption and COM2 short connection. COM22-channel relay common interface.; Third, the technical parameters
Relay version: 12V;
Static current: 5mA;
MAX current: 50mA;
Trigger current: 2-4mA;
Trigger voltage (low): 0-8V;
Trigger voltage (high): 8.5 -24V; High and low level trigger selection terminal 1. S1 is 1-channel relay high and low level trigger selection. 2. S2 is 2-channel relay high and low level trigger selection.
3. When com and low are shorted, the corresponding relay is triggered at low level, and when com and high are shorted.
