Functional Role / System Position
The 3500/61 module operates as a temperature acquisition interface within the monitoring rack:
Field Temperature Sensors (RTDs/Thermocouples) → 3500/61 Module → Rack Data Bus → Controller Logic → Alarms / Recorders
It captures low-level analog temperature signals, conditions them, and forwards processed measurements to controllers and monitoring systems. Each module supports multiple channels, providing comprehensive coverage of critical machinery points while safeguarding controller inputs through isolation and signal conditioning.
Key Features / Functional Capabilities
■ Six independently configurable temperature channels supporting RTD and thermocouple inputs
■ Programmable alarm thresholds for both warning and danger levels
■ 4–20 mA recorder outputs for continuous monitoring and trend analysis
■ Electrical isolation between channels for enhanced signal integrity
■ Robust design suitable for industrial operating conditions
■ Supports integration into redundant architectures for higher reliability
Application Areas / Typical Use Cases
The 3500/61 module is ideal in industrial settings requiring precise temperature monitoring for machinery protection:
- Bearing and shaft temperature monitoring on turbines, compressors, and pumps
- Process fluid temperature measurement in chemical or power generation plants
- Heat exchanger and boiler monitoring for process control
- Data acquisition for predictive maintenance programs
- Integration into larger machinery protection and control systems
