Technical Specifications Input Channels: Multiple temperature input channels Signal Type: RTD and thermocouple signal optional Power Supply: Powered by rack backplane Operating Temperature: 0℃ ~ +60℃ Mounting: 3500 rack slot mounting Housing: Metal rack card casing
Functional Features Multi-channel temperature signal acquisition for multiple measuring points. Compatible with RTD and thermocouple sensor input. Real-time temperature calculation and threshold comparison for alarm and trip. Built-in sensor open circuit and short circuit fault diagnosis. Hot swappable for online maintenance. LED indicators for each channel working and alarm status.
Application Scenarios Bearing metal temperature monitoring of turbine, gas turbine and compressor. Generator stator and rotor winding temperature supervision. Casing and lubricating oil temperature measurement for power plant units. Petrochemical plant critical rotating equipment temperature protection. Heavy industrial rotating machinery multi-point temperature condition monitoring.
Performance Parameters Measurement accuracy: High precision temperature sampling Fault diagnosis: Detect temperature sensor and wiring failure Data transmission: Upload temperature value and alarm status to rack interface
Structural Characteristics Standard rack card metal casing. Internal signal conditioning, sampling and temperature conversion circuit. Backplane connector for power and data exchange with rack backplane. Front panel sensor input terminals and channel LED indicators. Front panel locking structure.
Working Principle Temperature sensors transfer resistance or voltage signal corresponding to temperature to module terminals. Internal circuit processes and converts raw sensor signal into actual temperature value. The module compares measured temperature with preset alarm and trip limits, outputs protection logic signal and uploads all data to rack interface module.
Installation Requirements Insert module into specified slot of 3500 rack and lock front panel. Confirm backplane connector fully contacts rack backplane. Connect RTD or thermocouple shielded wire to front input terminals. Select sensor type and set temperature threshold via configuration software. Check channel status indicators after power on.
