8 Channel High Trip 5V 10A Relay Module

This module is a three way switch ( COM, NO and NC ) that uses the intensity of the ambient light to control directly the load at the output. Its adjustment potentiometer allows changing the sensitivity and setting the start threshold of the relay. The relay is energized when it is darker than the threshold.

Relay Module DC 5V 10A 2 Channel Low/High Trigger features:
- Channels: 2 (independent protected with Optocouplers)
- Supply voltage: 5V
- Output Current: 10A
- Relay activation current: 15mA ~ 20mA
- Insulation: Yes
- Trigger signal type jumper (low / high)
- LED indicator: For each channel
- Dimensions: 40x 50mm
- It has a jumper that allows to choose type of trigger signal (low / high)
- This module can be controlled directly by the microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL)

SPM-4Relay - stackable power meter (slave) realizes smart management with overload protection, metadata monitoring and electricity statistics. Up to 32 SPM-4Relays can be connected to one SPM-Main. Each SPM-4Relay has 4 isolated channels for better device management. You can monitor power consumption using the eWeLink app on your mobile phone. Each channel supports a maximum current of 20A. The SPM-Main communicates with the SPM-4Relays via RS-485, allowing multi-terminal and stable data transmission over long distances. It comes with overload protection to protect from burning out.

The multifunctional relay control module, FRM01, is designed for customers with different synchronization and control needs.
The FRM01 is controlled by the STM8S003F3P6 microcontroller and has 18 different functions.
Each function can be customized to meet customer needs in a variety of time and power control applications.
The FRM01 is equipped with a high-quality power relay, a high-power voltage transistor, red and blue LED indicators, an LED display on a double-sided PCB board.
The output of the board is driven by a high quality power relay capable of controlling the AC and DC loads. Timer Relay Module FRM01 features:
- Operating voltage: 12 VDC
- 4 buttons: SET, SWI, NUM +, NUM-
- Operating temperature: -20 °C - + 60 °C
