Description
The
HE693RTD660 is a precision-engineered
RTD (Resistance Temperature Detector) input module designed for GE’s Mark VIe and Mark VIIe gas turbine control systems. Optimized for high-accuracy temperature measurement in critical industrial applications, this module supports multiple RTD types and offers robust signal conditioning for reliable data acquisition.
- Function: Converts RTD sensor signals into digital data for temperature monitoring and control.
- Key Features:
- Supports 8 channels of isolated RTD inputs (2-, 3-, or 4-wire configurations).
- Compatible with PT100, PT200, PT500, and PT1000 sensors.
- Built-in linearization and cold-junction compensation.
- Hot-swap capability for maintenance flexibility.

HE693RTD660
- Sensor Compatibility: Verify RTD type (e.g., PT100 vs. PT1000) and wire configuration.
- Environmental Conditions: Choose modules with EMI shielding for noisy environments.
- Redundancy: Pair with dual RTD sensors for critical temperature measurements.
- Wiring: Use twisted-pair cables with proper termination resistors for 3/4-wire RTDs.
- Calibration: Perform biannual checks using GE’s calibration tools.
- Firmware Updates: Regularly update firmware to ensure compatibility with control system upgrades.
