Detailed content
-
- Operating Temperature: 0°C to 60°C
- Storage Temperature: -40°C to 85°C
- Relative Humidity: 5% to 95% non-condensing
- Shock Resistance: 15 g peak (IEEE 344)
- Vibration Resistance: 0.5 g RMS, 5 Hz–200 Hz (IEEE 344)
- EMC Compliance: IEC 61000-6-2 industrial immunity
- Enclosure: Die-cast aluminum alloy with powder-coat finish
- PCB: FR-4 multilayer with conformal coating
- Dimensions: ≈25 mm × 120 mm × 140 mm (W × H × D)
- Functional Characteristics
- Cold-junction compensation (CJC) for thermocouple signal acquisition
- Open-circuit and short-circuit detection with automatic alarm
- Signal Quality Monitor for real-time signal integrity assessment
- Configurable 50 Hz / 60 Hz notch filter per channel
- Hot-swappable replacement without affecting adjacent modules
- Structural Features
- 8 channel-status LEDs on front panel
- 32-pin high-density D-type rear connector for backplane bus
- DIP switch on top for address and configuration selection
- Spring-type screw terminals, nickel-plated
- Application Scenarios
- Gas turbine generator control
- Steam turbine generator control
- Industrial gas turbine compressor drives
- Petrochemical process control
- Installation Requirements
- Install in designated slot of GE Mark VI terminal base (e.g., TKMA31000WL)
- Use shielded twisted-pair wiring; shield grounded at single point
- Separate analog and digital signal cables by ≥100 mm
- Set module address via DIP switch, range 0–7; no duplicate addresses on same base
- Usage Notes
- Do not exceed 30 V DC or 25 mA input to avoid A/D converter damage
- Enable cold-junction compensation for thermocouple inputs to prevent >10°C measurement error
- Execute channel calibration via ToolboxST software at 12-month intervals
- On module fault, corresponding channel automatically holds last valid value
