Function & Performance Features

1. Dual-purpose real-time processing: support industrial logic control and high-precision weighing signal synchronous acquisition
2. Multi-channel synchronous weight data processing, up to 30 weighing channels synchronized sampling with 110 Hz refresh rate
3. Hardware watchdog circuit, automatic system reset when program crash or deadlock to avoid production line halt
4. Rich expandable industrial bus interfaces, seamless connection with PLC, touch screen, weighing sensor and frequency converter
5. Modular compact design, low power consumption, no fan passive cooling, suitable for sealed cabinet installation
6. Customizable secondary development interface, support user self-programming control logic via standard industrial programming software

Working Principle

1. High-speed ADC chip collects analog signals from weighing pressure sensors or industrial temperature/flow sensors
2. ARM real-time processor executes user-programmed control logic, compute weight data and output corresponding control pulse signals
3. Gigabit Ethernet and RS485 bus upload processing data to upper monitoring HMI and central DCS host
4. Hardware watchdog continuously monitors processor operation state, trigger automatic reset if program stops responding
5. Onboard eMMC storage stores production data, fault logs and user control program for power-off data retention

Material Composition & Structural Characteristics

• Circuit Board: High-temperature FR4 multilayer PCB with full conformal coating, anti-humidity and anti-dust
• Outer Shield Shell: Thin aluminum alloy shielding frame, reduce external electromagnetic signal interference
• Terminal Interface: Spring-type anti-loose industrial wiring terminal, vibration resistant for long-term factory operation

Installation Requirements

1. Install on standard 35 mm DIN rail inside industrial control cabinet, reserve 10 mm gap between adjacent modules for heat dissipation
2. Analog sensor signal wire must use shielded twisted pair, separate wiring trough from power cable to avoid sampling noise
3. 24 VDC power supply input needs to add external surge absorption diode for voltage fluctuation protection
4. Cabinet internal temperature must not exceed 70 °C, install heat exchanger if long-term full load operation

Application Scenarios

• Food processing online weighing and batching control
• Chemical industry raw material proportioning DCS control system
• Automated logistics weighing sorting equipment
• Cement building material mixing station weight monitoring
• Water treatment process flow parameter real-time acquisition control

Usage Precautions

1. Do not install near high-power frequency converters and contactors, strong electromagnetic interference will cause analog sampling distortion
2. Back up user control program and production data every month to eMMC storage or external SD card
3. Avoid static electricity contact with PCB circuit board during maintenance; wear anti-static wrist strap
4. Do not connect analog input terminal to high-voltage circuit by mistake, will burn internal ADC sampling chip
