Technical Specifications:
- Channel number: 6 measuring channels, each channel with independent 4‑20mA recorder output
- Input signal: RTD 3‑wire/4‑wire Pt100, multi‑type thermocouple
- A‑D conversion: 24‑bit high‑precision sampling
- Recorder output: 4‑20mA proportional analog signal per channel
- Operating temperature: ‑30°C ~ +65°C
- Storage temperature: ‑40°C ~ +85°C
- Power consumption: Max 8.0W
- Available I/O variant: Non‑isolated internal termination (01 order variant) Functional Features:
- Support mixed RTD and thermocouple signal input among six channels
- Built‑in cold‑junction compensation for thermocouple measuring loop
- Each channel configurable warning and trip temperature threshold
- Per‑channel independent 4‑20mA analog output for recording instrument or DCS analog acquisition
- Complete self‑diagnosis for sensor open‑circuit, short‑circuit and module hardware fault
- Support TMR triple redundant installation configuration for high‑safety rotating equipment
- All measurement value, alarm status and fault information transmitted to rack internal bus for gateway uploading Application Scenarios: Turbine, centrifugal compressor, generator set in petrochemical and power industry, which need temperature protection and meanwhile require analog 4‑20mA local recording; bearing metal temperature, motor stator temperature, process gas temperature monitoring application scenariosBaker Hugh… Performance Parameters: High‑precision temperature measurement; 4‑20mA output corresponds to full measuring range of each channel; real‑time fault diagnosis for sensor loop; software full‑channel parameter configuration Material Composition: Front panel: Anodized aluminum alloy housing; circuit substrate: Industrial FR‑4 PCB board; analog output driving chip, high‑precision reference component; gold‑plated high‑density backplane connector for rack bus connection Structural Characteristics: Standard full‑height plug‑in card for 3500 rack front‑side slot; front panel with LED state indication lamp; rear end mates with rack rear‑side I/O termination module; fixed by anti‑vibration locking screw Working Principle: Temperature sensors convert physical temperature into resistance or millivolt analog signal. Module executes signal conditioning, cold‑junction compensation and high‑precision A/D conversion, calculates actual temperature value. On one hand, compare temperature reading with alarm threshold to trigger protection alarm flag; on the other hand, convert temperature value into corresponding 4‑20mA analog current signal output for external recording equipment. All data and status upload to rack backplane bus for system communication gateway processing。 Installation Requirements:
- Implement anti‑static protection when inserting module into rack slot, cut off rack power supply during hardware installation
- Match correct rear‑side I/O termination module corresponding to order suffix‑01
- Thermocouple must use special compensation cable, RTD strictly follow 3‑wire /4‑wire wiring specification
- 4‑20mA recorder output wiring should use shielded twisted‑pair cable, separate routing from power cable
- After hardware installation, download configuration file by 3500 rack configuration software, confirm sensor type and 4‑20mA range mapping parameter for each channel Usage Precautions:
- Prevent multi‑point grounding for sensor circuit to avoid ground‑loop interference causing measuring error
- Do not short‑circuit 4‑20mA output terminals for long time
- Back‑up complete configuration file after commissioning
- Check fault event log regularly, resolve sensor wiring aging and damage in time
- Cabinet should keep dry and dust‑proof working environment
