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

Primary function

Supports sending Modbus RTU protocol commands via RS485
to acquire data from 0~20mA/0~10V sensor

Industrial Grade Isolated Protection

Onboard power and signal dual isolation for RS485 communication, provides stable isolation voltage, features high reliability and strong anti-interference performance. Built-in TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient peak voltage in the circuit, lightningproof & ESD protection. Built-in resettable fuse and protection diode to ensure stable current and voltage output, provides over-current and over-voltage proof, improves shock-proof performance, suitable for the industrial environments with high requirement.

Supports voltage/current acquisition
Wider Measurement range

8-ch analog acquisition interfaces, voltage and current acquisition is switchable via jumper. Multiple Ranges Configurable via Software
