16 Channel Relay Module Optocoupler Compatible with Arduino

1 The relay contact capacity is 10A 250V, with optocoupler protection. The onboard power module does not require an external power supply, IO port drive active high 2 Can be used as a single chip development board module, as home appliance control, and also as a PLC expansion output 3 Using industry isolation optocoupler, possess strong anti interference ability and stable performance, trigger current only needs 3mA 4 1-16 channels can be turned on or off arbitrarily, or any channels. The output can be directly connected to the load of AC 220V 10A or DC30V 10A 5 The common terminal COM of each relay is independent, which is convenient for users to access different signals. Each relay has a normally closed and normally open port 6 There are 4 fixing bolt holes for easy installation. Each relay has an action indicator light, which on when it is on, and off when it is off 7 The interface design is humanized, all interfaces can be directly connected through the terminal block, which is very convenient
