Working Principle

Each independent channel supplies isolated stabilized 5 VDC excitation voltage to individual strain gauge load cells; low-noise instrumentation amplifiers amplify micro-magnitude mV/V strain signals; dedicated 24-bit ADC per channel converts analog strain measurement to digital weight values; independent digital filtering logic suppresses mechanical vibration noise for each weighing channel; calibrated weight datasets packaged into Modbus RTU protocol and transmitted via dual RS485 communication buses to external industrial automation PLC controllers; continuous per-channel circuit monitoring identifies load cell wiring faults and overload weight conditions with dedicated fault register output.

Advantage Highlights

  1. 8 high-density isolated load cell measurement channels drastically reduces total DIN rail cabinet space requirement for multi-hopper batching systems
  2. Fully independent per-channel calibration and filtering settings accommodate mixed model load cell configurations on single module
  3. Dual redundant Modbus communication ports enable simultaneous weight data transmission to primary and backup control PLC systems
  4. Channel galvanic isolation eliminates cross-talk interference between adjacent weighing tank load cell circuits
  5. Comprehensive per-channel diagnostic fault reporting accelerates multi-weighing system field maintenance

Applicable Industries

Large-scale chemical bulk ingredient blending, feed mill multi-hopper automated mixing, mineral raw material multi-tank weighing, food production multi-component continuous batching, pharmaceutical multi-powder simultaneous formulation

Installation Requirements

  1. Mount module onto standard 35 mm top-hat DIN rail within climate-controlled industrial electrical cabinet
  2. Each load cell channel requires dedicated 4-wire shielded strain gauge signal cable; single-point shield grounding at cabinet terminal strip
  3. Separate all low-level load cell wiring by minimum 30 cm distance from high-power AC control cables
  4. 24 VDC power supply input must feature low ripple filtered DC output with maximum ripple ≤ 50 mV peak-to-peak
  5. Maintain minimum 20 mm horizontal clearance between MDB-8E and adjacent heat-generating DIN rail modules

Usage Precautions

  1. No channel shall be connected to load cell transducers exceeding maximum 3.0 mV/V sensitivity rating
  2. Avoid installation in cabinet locations exposed to continuous mechanical vibration or direct radiant heat
  3. Disconnect all load cell wiring terminals prior to executing full module factory calibration reset
  4. Prevent dust or liquid ingress into IP30 rated enclosure housing during cabinet maintenance operations
  5. Re-execute per-channel linear calibration after any load cell replacement or field wiring modification
