Gravity: Analog Signal Isolation Module

SKU: DFR0504

The Gravity Analog Signal Isolation Module is vital for maintaining signal integrity in electronic systems, operating on a 5.0V supply with minimal analog error between two terminals, featuring a 4-second response time and PH2.0-3P connector type, designed for efficient integration into various projects. It includes two primary terminals: the non-isolation terminal (MCU Terminal) and the isolation terminal (SEN Terminal), each with specific supply voltages and analog input/output ranges, emphasizing the importance of connecting the SEN terminal to sensors or modules and the MCU terminal to the main control board. This module enables users to achieve reliable signal isolation, enhancing the overall performance of electronic systems.

    FAQ

    • Hi DFRobot, can I use this voltage isolator with the SEN0198 High Temperature probe? Since it has an analog output to for the resistance at a given temperature. And I am using the SEN0198 with other sensors with analog output also.

      You can just use one DFR0504 if you have one pH and one EC sensor, and this module doesn't need to code, just plug between one sensor and Arduino
