12V 5V 30A Two-Way Isolation Relay Module High/Low Level Trigger 12V/5V 1-Channel +Electronic with Optocoupler(12v)

relay5V 30A Two-way isolation relay module High/low level trigger 5V 30A 1-Channel Relay ModuleTwo-way isolation type 1 road power relay control module, can choose high level or low level signal trigger, and only 3 ma current drive for 30 a relay and control ability, module adopts quality goods of high quality power relay, the industry's top subminiature encapsulation light coupling, high power high pressure triode, red, blue light signal, military level double-sided PCB board, cloth plate considering comprehensive, stable performance and can be widely used in all kinds of power control class. Module specification1, the module used authentic quality relay, normally open interface maximum load: ac 250 v / 30 a, dc 30 v / 30 a;2, using the industry's top quality subminiature two-way isolation optical coupling, strong anti-interference ability, stable performance;Trigger current only 3 ma.3, modules, working voltage is 5V, 12V and 24V are available;4, the user can choose the relay control level, can be a high level off, also can be low level and off;Module contains a limited flow resistance, can directly use the power supply is negative control, you can also use the MCU I/O control;5, fault-tolerant design, even if the control line is broken, relay will not move; 6, the power indicator light (red), 1 road relay status indicator light (blue)7, human interface design, all interface can be directly by terminal connection leads, is very convenient8, module size: 6.0 cm * 3.0 m * 2.5 cm (length * width * height)9, is equipped with four fixed bolt hole, convenient installationThe second module interfaceInterface module control side: there are 4 line, all interfaces are terminal blocks, easy connection1, DC + : external DC power anode (5V, 12V and 24V module selection)2, DC - : external negative DC power supply3, VREF, photoelectric isolation reference ground control end,If using high level contro
