Images are for illustration purposes only. E&OE Overview 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. Features 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 Specifications Model Modbus RTU Analog Input 8CH Communication interface RS485 Baud rate 4800, 9600, 19200, 38400, 57600, 115200, 128000, 256000 Default communication format 9600, N, 8, 1 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 current mode, 0~20mA Range 0~5V/1~5V0~20mA/4~20mA current Sampling resistor 249Ω References
