Description
ABB TTH300-Y0
Technical Specifications:
- Model: TTH300 Series (Y0 Variant: No explosion protection)
- Communication Protocol: HART, programmable, 4-20 mA output
- Configuration: Standard configuration (BS)
- Display Option: Configurable LCD indicator type A (D4)
- Documentation Language: English (M5)
Functional Features:
- Universal Sensor Input: Supports two universal inputs for RTD (Pt100), thermocouples, resistance (Ω), and millivolt (mV) signals.
- Functional Safety: Complies with IEC 61508 SIL 2/SIL 3 safety standards.
- Advanced Calibration: Supports one-point, two-point, Callendar-van-Dusen, and free-form characteristic calibration with up to 32 support points.
- Sensor Redundancy: Features automatic switching for sensor backup (e.g., 2 x Pt100 3-wire connection).
Application Scenarios:
Widely used in process industries for accurate temperature monitoring in non-hazardous environments, integrating seamlessly with DCS and PLC systems.
Performance Parameters:
- Accuracy: Exceptional 0.1% overall accuracy.
- Long-term Stability: 0.05% per year.
- Protection Level: IP20 (for integration into DIN A/B sensor junction boxes).
Material Composition:
Features a microprocessor-controlled electronic assembly housed in a robust, thermally stable enclosure suitable for DIN junction box integration.
Structural Features:
Compact head-mounted design with a 6-pin flat cable connector for optional LCD display integration.
Working Principle:
Digitizes the raw analog signal from the temperature sensor, applies linearization and compensation algorithms via the microprocessor, and outputs a highly accurate 4-20 mA signal with superimposed HART digital communication.
Installation Requirements:
Install directly into a standard DIN B-type sensor junction box. Ensure proper thermal coupling with the process.
Usage Precautions:
Use DTM or EDD software for configuration. Verify the sensor type matches the transmitter configuration before commissioning.
