16 channel relay DC 5V / 12V / 24V

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

The relay is able to control various devices and other equipment with high energy requirements.

Uses two 8-channel ULN2803APG Darlington array chips to control the relay module.

The maximum switching 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 operating status indicator lights are for safe use.

Widely used for all MCU controls, industrial areas, PLC controls, smart home controls.

4 mounting holes for easy installation.

Notes:

Relays 6,7,10 and 14 are always switched ON and OFF when the board is powered, causing a brief on/off pulse on the relay as Tasmota charges it and turns 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. Alexa or app control via the outdated FriendlyNames, however, is only limited to the first 8 channels.
