- Cold junction compensation function for thermocouple measurement
- User programmable high‑alarm, high‑high‑alarm threshold for every channel
- Channel open‑circuit, short‑circuit fault self‑diagnosis
- Temperature measurement value and channel fault status transmit to rack backplane bus for gateway uploading to DCS/SCADA system
- Supports triple modular redundant TMR installation mode for high‑safety application Application Scenarios: Monitor radial bearing, thrust bearing metal temperature of turbine, compressor, generator; motor stator winding temperature; compressor suction‑discharge gas temperature; steam pipeline temperature in power, petrochemical, metallurgy industry rotating machinery protection systemBaker Hugh… Performance Parameters: High‑precision temperature sampling; supports absolute temperature monitoring and temperature‑difference monitoring; fault self‑diagnosis real‑time detection of sensor wiring abnormal; all channel parameters configurable by 3500 rack configuration software Material Composition: Main circuit board: Industrial FR‑4 printed circuit board; front panel: Anodized aluminum alloy; backplane connector: Gold‑plated European‑style high‑density connector; internal chips: Industrial‑grade analog acquisition chip, MCU control chip, high‑stability reference resistance Structural Characteristics: Full‑height front plug‑in card for 3500 rack; front panel with LED channel status indicators; rear side connects with matched rear termination I/O module of rack; locked by mounting screws to resist mechanical vibration from industrial site Working Principle: RTD converts temperature value to resistance variation, thermocouple converts temperature difference to millivolt voltage signal. The module conditions analog input signal, completes cold‑junction compensation for thermocouple, performs 24‑bit A/D conversion, converts digital signal to actual temperature reading. Compare reading with preset alarm threshold, generate alarm flag when exceeding set‑point, transmit alarm status to rack bus and relay output module。 Installation Requirements:
- Power off rack before installation, wear anti‑static wrist strap
- Insert into correct rack front slot, must match corresponding rear termination I/O module (internal termination or external termination version) at rack rear side
- Sensor signal wiring shall adopt dedicated compensation cable for thermocouple; RTD shall strictly follow 3‑wire or 4‑wire wiring requirement
- Avoid ground loop interference, keep unified ground reference for all temperature sensors
- After hardware installation, download channel configuration file via 3500 configuration software, confirm sensor type setting for each channel Usage Precautions:
- Non‑isolated version module needs to prevent multi‑point grounding of sensor cables to avoid ground loop leading to measurement drift
- For thermocouple channel, keep rear I/O module good heat dissipation to guarantee cold‑junction compensation accuracy
- Do not apply over‑range voltage to analog input channels
- Regularly check channel fault log, timely handle sensor wiring aging problem
- Back‑up configuration file after completing parameter setting for convenient fault recovery
