Article description:

16 Channel Relais DC 5V / 12V / 24V

It is a 16-channel relay interface card that can be controlled directly from a wide range of microcontrollers such as Arduino (8051, AVR, PIC, PLC, DSP, ARM, MSP430, TTL logic).

The relay is able to control different devices and other equipment with a high energy requirement.

Uses two 8-channel Uln2803Apg Darlington array chips for controlling the relay module.

The maximum circuit value of the relay output is AC250V 10A and DC30V 10A.

Optocoupler with industrial insulation. Strong anti-interference ability. The trigger current is only 3MA.

The display shells for the operating state are used for safe use.

Widespread for all MCU controls, industrial areas, PLC controls, smart home controls.

4 fastening holes for easy assembly.

Hints:

The Relays 6,7,10 and 14 are always switched ON and OFF when the board is powered, which causes a short ON/OFF pulse on the relay when Tasmota charges it and switches it OFF again. If the last state was ON, then of course it remains ON.

All 16 channels could be controlled via the following interfaces: serial, webgui, MQTT, http. An Alexa or app control over the outdated friends of friends, but is limited to the first 8 channels.
