The BOKRA I2C 4RO SRD is 5VDC powered quad relay board. It is a very useful power accessory that has been developed to switch four individual high powered devices from your Rapberry, Arduino, Nucleo, Adafruit, Teensy and more using I2C bus. This relay board has four SRD-05VDC-SL-C relays.

Rated resistive load: 7A at a voltage of 240 VAC or 28 VDC. Contact form - SPDT. The galvanic isolation is individual. The dielectric strength of the insulation is 1,5 kV AC (for one minute between the coil and the contacts) and 1 kV AC (for one minute between the contacts of the same polarity).

There is an indication of the status of relays.

The BOKRA I2C 4RO SRD module is controlled via the I2C protocol using the MCP23008 chip. Therefore, it belongs to the I2C relay board. An alternative control method is directly via signals via an auxiliary connector. These control methods allow you to use the module with almost any type of microcontroller. This relay board compatible with Rapberry, Arduino, Nucleo, Adafruit, Particle, Teensy and more with or without I2C bus.

The BOKRA I2C 4RO SRD module size 65 x 56 mm. The format of the module corresponds to the popular format of the Raspberry Pi 3A+, which greatly simplifies its use with the Raspberry Pi. Therefore, the BOKRA I2C 4RO SRD is first of all the Raspberry Pi relay board.

The relay module comes fully assembled and ready to go. The module is part of the BOKRA universal platform for IoT and IIOT, which was created to simplify users the step from design to implementation of projects and the start of production.

The main areas of application of the BOKRA I2C 4RO SRD quad relay board:

• Industry and Equipment
• Consumer electronics and devices
• Smart home
• Data acquisition systems (DAS) and PLC
• DC motor control
• Lighting
• Power On/Off
• Heating, Ventilation, & Air Conditioning (HVAC)
