The module uses genuine high-quality power relays, the industry ’ s top ultra-small packaged optocouplers, high-power and high-voltage transistors, red signal indicators, military-grade double-sided PCB boards, comprehensive board layout considerations, stable performance, and can be widely used in various Power control occasions I. Module description The module uses genuine high-quality relays, AC 125V\/20A, DC 14V\/20A; Using the industry's top quality ultra-small two-way isolation optocoupler, strong anti-interference ability and stable performance; The working voltage of the module is 5V; there are 1 way, 2 way, 4 way, 8 way, 16 way module to choose from; The user can select the control level of the relay, which can be high-level pull-in or low-level pull-in; the module contains a current-limiting resistor, which can be directly controlled by the positive and negative electrodes of the power supply, or the I of the microcontroller \/O port control; Fault-tolerant design, even if the control line is broken, the relay will not act; The interface design is humanized, all interfaces can be directly connected through the terminal block, which is very convenient; There are 4 fixing bolt holes for easy installation; Relay status indicator (red) II. Module interface Module input control terminal DC+: External DC power supply positive DC-: External DC power supply negative VREF: Reference ground wire of optoelectronic isolation control terminal, If high level control is adopted: this signal should be connected to the negative terminal of the power su.Find many great new \u0026amp; used options and get the best deals for New 5V 20A 2 Channel Relay Control Module Support High And Low Voltage Trigger at the best online prices at Order2india Shopping!
