T8110C
Product Name
T8110C 8-Channel High-Precision RTD Input Module (Industrial Temperature Measurement Dedicated)
(Naming convention explanation for temperature input modules:
- “T”: Denotes “Temperature” to clarify its core function in temperature signal acquisition.
- “8110”: Model-specific code: “8” indicates 8 independent input channels; “110” specifies RTD sensor compatibility (vs. “210” for thermocouples).
- “C”: Variant identifier for “Commercial/Industrial” grade, optimized for general-purpose process environments (distinguished from “H” for hazardous areas).
- Core positioning: Acts as the “temperature signal converter” between RTD sensors and control systems, delivering high-accuracy data for process monitoring and closed-loop temperature control.)
2. Product Description
The T8110C is an industrial-grade RTD input module engineered to address high-accuracy temperature measurement challenges in critical processes (e.g., pharmaceutical fermentation, food pasteurization, chemical reactor temperature monitoring). It excels at converting low-resistance signals from RTD sensors into stable, digitized data—overcoming common issues like lead resistance interference and electrical noise. Key capabilities include:
2.1 Multi-Channel RTD Compatibility
Supports diverse RTD types to adapt to varying temperature ranges:
- Compatible with industry-standard RTDs: PT100 (platinum, -200°C~+850°C), PT500 (-200°C~+850°C), and PT1000 (-50°C~+400°C)—covers most industrial temperature measurement needs.
- 8 independent, galvanically isolated channels (250V AC isolation between channels) to prevent cross-talk and ground loops, a critical feature when sensors are deployed across distributed process units.
2.2 Ultra-High Measurement Accuracy
Ensures reliable temperature data for regulatory compliance and process optimization:
- Features a 24-bit ADC (Analog-to-Digital Converter) with ±0.05°C accuracy at 0°C (PT100 sensor) and ±0.1°C accuracy over the full -200°C~+850°C range—meets strict standards for pharmaceutical (FDA) and food (FSMA) industries.
- Built-in 3-wire/4-wire RTD support: Automatically compensates for lead resistance (a major source of measurement error) in long sensor cables (up to 100m), eliminating the need for external signal conditioners.
2.3 Robust Noise Immunity
Stable performance in electrically noisy industrial environments:
- Complies with EN 61326-1 (industrial electromagnetic compatibility) and integrates a 50/60Hz notch filter to suppress interference from nearby motors, VFDs, or power grids.
- Surge protection (6kV ESD contact, 8kV ESD air) on all input channels to safeguard against voltage spikes from sensor wiring faults or lightning-induced transients.
2.4 Flexible System Integration
Seamless connectivity with industrial control systems:
- Supports communication via Modbus RTU (RS-485) and EtherNet/IP (optional), enabling real-time data transmission to PLCs (e.g., Allen-Bradley ControlLogix) and SCADA systems (e.g., Ignition).
- Configurable via front-panel DIP switches or software (e.g., module configuration tool), allowing users to set RTD type, sampling rate (100ms~10s), and alarm thresholds without specialized programming.
