Description
Honeywell CC-TAIX51 Analog Input Module
I. Core Functions
Analog Signal Digital Conversion
- Converts analog signals in industrial fields (such as 4-20mA current, 0-10V voltage, thermistor/thermocouple temperature signals, etc.) into digital signals for processing by control systems like PLC and DCS.
- Supports multi-channel synchronous acquisition to meet the needs of real-time monitoring of multiple parameters.
Signal Conditioning and Processing
- Built-in filter circuit suppresses field electromagnetic interference (EMI) and radio-frequency interference (RFI) to ensure signal stability.
- Supports linearization processing (such as thermocouple cold junction compensation and non-linear signal correction) to improve data accuracy.
HART Communication Integration
- Some models have built-in HART protocol for bidirectional communication with intelligent instruments, enabling parameter configuration, device diagnosis, and data calibration.
II. Product Features
| Features | Details |
|---|---|
| High-precision acquisition | Accuracy reaches ±0.1% FS, with a maximum resolution of 16 bits (0.01% full scale), suitable for precision control scenarios. |
| Multi-channel design | Common channel numbers: 4/8/16 channels, supporting hot standby redundancy configuration to enhance system reliability. |
| Electrical isolation | Isolation voltage between channels and between input/output ≥1500Vrms, preventing ground loop interference and surge impacts. |
| Wide temperature and anti-interference | Operating temperature -40°C~+70°C, protection level IP65/IP67 (depending on the model), adapting to harsh industrial environments (dust, moisture, vibration). |
| Flexible configuration | Configures parameters such as range, filter time constant, and disconnection detection threshold through software (such as Honeywell Experion) or field buttons. |
III. Technical Parameters
| Parameter Category | Specific Indicators |
|---|---|
| Input type | Current: 4-20mA, 0-20mA, ±20mA; Voltage: 0-5V, 0-10V, ±10V; Thermistors (Pt100, Ni100, etc.), thermocouples (J/K/T/E, etc.). |
| Sampling rate | Single channel up to 500Hz (depending on the model), supporting custom channel scanning period. |
| Response time | ≤1ms (signal stabilization time), meeting real-time control requirements. |
| Communication interface | Supports protocols such as Modbus RTU, HART 7.0, and Profibus DP (communication module needs to be selected). |
| Certification standards | Complies with international standards such as UL, CSA, CE, and ATEX (explosion-proof certification), suitable for hazardous areas (such as Zone 1/21). |
