Sense high voltage inputs.

Fast AC-TTL sensing response.


B301-CA is an voltage / current treshold detection module for using high voltage detections (220V). Module allows you to test for the presence of 220V mains. The output is opto-isolated so you can safely connect it to any electronic circuit without risk of damage or bodily harm.

It is fully compatible with all microcontrollers, Arduino or PLC systems. 220V detection system is controlled by 8 channel I2C I/O expander module. Module communicates the MCU with I2C protocol. B301 is compatable to ultra low power consumption systems.
