  • Industrial 8-Ch Analog Acquisition Module (B), 12-bit , 0~10V (default) / 2~10V / 0~20mA /4~20mA

    Modbus RTU Analog Input 8CH is an industrial standard analog acquisition module, supports multiple ranges and 8-ch simultaneous acquisition. Adopts Modbus RTU protocol with built-in protection circuits such as power isolation, magnetical isolation, resettable fuse, and TVS.


    User Manual / Datasheet / Example Codes Etc.



    •  Configurable device address (1~255), multi devices can be cascaded on RS485 bus

    •  Onboard voltage regulator, supports 7~36V wide range power supply

    •  Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal

    •  Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference

    •  Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, provides            over-current/over-voltage proof, lightningproof & anti-electrostatic

    •  Supports 12-bit high-precision acquisition with multiple range input modes, supports single-ended/differential input, supports voltage and current                      simultaneous acquisition

    •  Adopts high-precision resistors and zero-drift high-precision operational amplifier for more accurate data acquisition

    •  Built-in oversampling digital filtering algorithm, onboard watchdog, for stable output without crashing

    •  Rail-mount case design, support stacking combination, easy to install and safer to use

    •  3x LEDs for indicating the MCU status and signal transceiving status




    •  BAUD RATE : 4800, 9600, 19200, 38400, 57600, 115200, 128000, 256000


    •  MODBUS PROTOCOL : Standard Modbus RTU protocol

    •  POWER SUPPLY : DC 7~36V

    •  SAMPLING ACCURACY : 12-bit resolution, accuracy ≤3%

    •  DATA UPDATE RATE : 25Hz

    •  INPUT MODE : supports single-ended/differential input, supports voltage and current simultaneous acquisition

    •  DEFAULT MODE : 8-ch voltage mode, 0~10V

    •  RANGE :  0~10V/2~10V , 0~20mA/4~20mA
