Description

Industrial 8-Channel Analog Acquisition Module

 

  • 12-bit High Precision
  • Supports Voltage and Current Acquisition
  • DC 7~36V Wide Voltage
  • Supports MODBUS RTU Protocol
  • Multiple Isolation Protection

 

 

Features at a Glance

MODBUS RTU Analog Input 8CH is an industrial standard analog acquisition module, that supports multiple ranges and 8-channel simultaneous acquisition, 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 a 7~36V wide-range power supply
  • Onboard unibody power supply isolation, provides stable isolated voltage. No extra power supply is needed 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
  • High-precision resistors and zero-drift high-precision operational amplifiers for more accurate data acquisition
  • Built-in oversampling digital filtering algorithm, and onboard watchdog, for stable output without crashing
  • DIN Rail-compatible case design, support stacking combination, easy to install and safer to use
  • LED indicators for indicating the MCU status and signal transceiving status

 

 

Modbus RTU Analog Input 8CH (B)
Supports four ranges (configurable):
0~10V (default)/2~10V
0~20mA /4~20mA

 

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, lightning proof & 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 industrial environments with high requirements.
