5V 12V 1 1 2 4 6 8 Channel Relay Module With Optocoupler 5V Relay Output 1 2 4 6 8 Way Relay Module For Arduino

1 Channel low level Feature: 1. There are isolation slots in the control zone and load zone. 2. With power and relay action indication, it lights up when connected, and disconnects when disconnected. 3. When the signal input has a signal, the common and common terminals will jump. 4. It can be used not only as a microcontroller development board module, but also as a home appliance control. 5. It can control not only DC or AC signals, but also 220V AC loads. 6. Has permanent opening and closing vent contact. 7. It is convenient to connect the blue KF301 terminal access control cable. Specification: 1. VCC: power interface, 5V 2. GND: Ground 3. IN: Control interface. Drive current at least 4mA 4. COM: Control circuit is grounded and connected to GND 5. Size: approx. 41×16×16mm / 1.61×0.62×0.62” 6. Weight: approx. 12g5V Relay Module 4-Channel This is a 5V 4-Channel Relay interface board. Be able to control various appliances, and other equipments with large current. It can be controlled directly by Micro-controller (8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) . 5V 4-Channel Relay interface board, and each one needs 50-60mA Driver Current. Equipped with high-current relay, AC250V 10A ; DC30V 10A. Indication LED’s for Relay output status.
