Material Composition

1. Outer shell: Cold-rolled steel plate with anti-corrosion black electrostatic coating
2. Main circuit substrate: FR4 high-temperature resistant multi-layer PCB board
3. Isolation component: High-speed optocoupler with industrial grade insulation encapsulation
4. Terminal connector: Copper alloy gold-plated pin terminals, anti-oxidation
5. Internal electronic components: Industrial-grade wide-temperature range operational amplifiers, precision metal film resistors, low-temperature drift capacitors

Structural Characteristics

1. Standard DIN rail pluggable card slot structure, hot-swap support under non-explosion hazardous area
2. Independent terminal wiring area separated from main circuit board, wiring space reserved for each channel
3. Front panel equipped with 8-channel independent signal status LED indicator lights + module power fault indicator
4. Internal layered heat dissipation structure, reserved air convection channels to avoid component overheating
5. Anti-vibration positioning buckle on both sides of the module, fixed locking structure after inserting backplane

Working Principle

1. Field analog signals enter each independent isolation channel through terminal wiring
2. Optocoupler realizes electrical isolation between field side and control bus side to eliminate ground loop interference
3. Precision operational amplifier completes signal filtering, amplification and range adjustment
4. 16-bit A/D chip converts analog signals into digital pulse signals
5. On-board MCU processes digital data, packages data according to Modbus RTU protocol
6. Transmits processed digital measurement data to Metso BIU8 main control backplane via internal bus
7. Real-time self-diagnosis circuit monitors channel open circuit, short circuit and overvoltage faults, outputs alarm signal via front LED

Core Function Features

1. Full-channel electrical isolation, zero crosstalk between adjacent measurement channels
2. Built-in hardware overvoltage, overcurrent and reverse power supply protection circuit
3. Multi-range signal automatic identification software configuration, no hardware replacement required
4. Real-time channel fault diagnosis function, accurately locate open-circuit/short-circuit field wiring faults
5. Compatibility with all standard industrial voltage and current transmitters
6. Modbus RTU industrial bus communication, seamless docking with Metso DCS system
7. Low-temperature drift circuit design, stable measurement accuracy under full operating temperature range

2. Wide temperature working range -40°C to +60°C, adapt to open-air mining and metallurgy factory environments
3. IP65 front panel protection, resist dust, splash water and workshop oil mist pollution
4. Lightweight compact design, reduce DCS cabinet space occupation
5. Hot-swap maintenance, no overall system shutdown during single module replacement
6. Long service life industrial electronic components, design service life up to 10 years continuous operation

Applicable Industries

Installation Requirements

1. Install on standard 35 mm DIN guide rail inside Metso BIU8 DCS control cabinet
2. Ambient operating environment must avoid direct sunlight, water splash and corrosive gas erosion
3. Keep ≥20 mm heat dissipation gap between adjacent modules for air circulation
4. Field signal wiring must use shielded twisted pair cables, cable shielding layer single-point grounding inside cabinet
5. Power supply must use regulated 24 V DC industrial power supply, voltage fluctuation range limited to ±10% rated voltage
6. For explosion hazardous working conditions, matched isolation safety barrier must be installed on signal front end

Usage Precautions

1. Strictly prohibit reverse connection of 24 V DC power supply terminals, otherwise permanent damage to internal power circuit
2. Input signal voltage/current cannot exceed maximum allowable range of each channel, over-range will burn optocoupler isolation components
3. Do not disassemble module shell without authorization, internal sealing and isolation structure will be damaged after disassembly
4. Regularly clean front panel LED and terminal dust every 6 months to prevent poor wiring contact
5. Storage environment must maintain dryness, long-term damp storage causes PCB circuit board corrosion
6. After module fault alarm, cut off field signal power supply first before replacing wiring or module
