Interface design of humanity, all interface can be connected directly leads to terminals, very convenient, is provided with 4 fixing bolt holes, convenient installation, use isolation optocoupler top quality, strong anti-interference ability, stable performance; trigger current of only 3mA. Products using LM2596S buck chip a slight fever, which is a normal phenomenon, relay long time work has fever normal, are a normal phenomenon;
Module application:
1, 12V relay contact capacity of 10A 250V, with optocoupler protection. Onboard power supply module does not need an external power supply. I/O export driven active low.
2, Can be used as MCU development board module, can be used as electric control, can also be used as a PLC extension output.
Other FeaturesPower supply voltage: 12V (DC) Power supply current: more than 200mA Each relay can load: 250V 10A (AC) or 30V 10A (DC)
