Industrial Modbus RTU 8-Ch Analog Data Acquisition 12-bit 0-20mA 0-10V

12-bit High-precision
Supports Voltage and Current Acquisition
Input DC 7~36V Wide Voltage
Modbus RTU Protocol
Multiple Isolation Protection

Features:

Modbus RTU Analog Input 8CH is an industrial standard analog acquisition module, that 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
The onboard voltage regulator, supports a 7~36V wide range power supply
Onboard unibody power supply isolation, provides stable isolated voltage, and 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, provide over-current/over-voltage proof, lightning proof & 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 amplifiers 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
