  Features At A Glance

  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.

  • 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
