5V Relay Module It is a 1 Channel/2 Channel/ 4 Channel/ 8 Channel 5V Relay Board Module. The relay normally open interface maximum load: AC 250V/10A, DC 30V/10A. It has a trigger current of 5mA, and module working voltage of DC 5V. Each channel of the module can be triggered by a jumper to set a high level or a low level. Fault-tolerant design, even if the control line is disconnected, the relay will not move. All module size interfaces can be directly connected through the terminal block, which is convenient and practical. 1 Channel Relay Module Features: 5V 1-Channel Relay interface board, and each one needs 15-20mA Driver Current Equipped with high-current relay, AC250V 10A ; DC30V 10A It has a relay status indicator led Power LED(Green), 1 relay status indicator LED(Red) Relay control interface by single-chip IO. Low-level suction close, high-level release. Easy to use, simple 3 line structure. Standard interface that can be controlled directly by microcontroller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) 2 Channel Relay Module Features : 2 LEDs to indicate when relays are ON. Works with logic level signals from 3.3V or 5V devices Opto isolation circuitry Module with diode current protection, short response time Around the board with 4 mounting holes, hole diameter 3. 1 mm, easy installation and fixing 4 Channel Relay Module Features : One normally closed contact and one normally open contact Triode drive, increasing relay coil High impedance controller pin Pull-down circuit for the avoidance of malfunction Power supply indicator and Control indicator lamp Power supply and relay instructions, lit, the disconnect is off; The input signal, signal, common Terminal and start conducting; Useful for appliance control; DC or AC signal, control, you can control the 220V AC load; There is a normally open and one normally closed contact; The module is compliant with international safety standards, control and load areas isolation trenches. 8 Channel Relay Module Features : Power supply and relay instructions, lit, the disconnect is off; The input signal, signal, common Terminal and start conducting; Useful for appliance control; DC or AC signal, control, you can control the 220V AC load. One normally closed contact and one normally open contact Triode drive, increasing relay coil High impedance controller pin Pull-down circuit for the avoidance of malfunction Power supply indicator and Control indicator lamp The module is compliant with international safety standards, control and load areas isolation trenches. Package Includes: 1 x 5V Relay Module (select option)
