IoTextra Relay2 - 4-channel SPDT relay module

The IoTextra Relay2 module has four Panasonic ALQ105, Omron G5Q-14, HF33F/005-ZS3 or TE PE014005 relays.

Contact form – SPDT (1 Form C). Switching Voltage: 250 VAC, 30 VDC. Contact Current Rating: 10A.

The galvanic isolation is individual. The dielectric strength of the insulation is 4000Vrms (for one minute between the coil and the contacts) and 750Vrms (for one minute between the opened contacts). Surge resistance between coil and contacts 8000V.

There is an indication of the status of relays.

There are two modes for using the IoTextra Relay2 module:

·   GPIO. In this mode, relay state control is carried out using signals AP0-AP3 in the HOST-P connector.

·   I²C. In this mode, relay state control is carried out on the serial I²C bus using an I/O expander (TCA9534 or compatible). Up to 16 modules can be connected to one I²C bus.

It is also possible to use AP0-AP3 signals in the HOST-P connector for some channels, and signals from the I/O expander for the rest.

Compatible with Raspberry Pi, Raspberry PICO, Arduino Nano, Nucleo, Adafruit, Teensy, ESP32, SeeedStudio XIAO and more.

Module size - 47 x 56 mm. The module has mounting holes for installation in the base module or Raspberry Pi.
