Usage Methods
- Installation:
-
- Mount the unit on a 35mm DIN rail in a control cabinet, ensuring a minimum of 10mm clearance around the unit for ventilation.
-
- Avoid direct exposure to extreme temperatures, strong magnetic fields, or corrosive gases. Secure the unit firmly to prevent vibration-induced loosening.
- Wiring:
-
- Connect temperature sensors to the input terminals, following the polarity markings for thermocouples. For RTDs, use 3-wire or 4-wire configurations to minimize lead resistance errors.
-
- Connect analog and digital outputs to the corresponding control or monitoring devices, ensuring proper wire gauge (0.5-1.5mm²) and tight terminal connections.
-
- Wire the power supply, ensuring correct polarity. Use shielded cables for sensor and communication lines, with shields grounded at one end.
- Configuration:
-
- Access the configuration menu via the front-panel buttons or software (using the RS485 or Ethernet interface). Set sensor types, measurement ranges, and filtering parameters for each channel.
-
- Configure output signals (range and type) and communication parameters (baud rate, parity, IP address for Ethernet).
-
- Set alarm thresholds for digital outputs to trigger alerts or control actions based on temperature limits.
- Operation and Maintenance:
-
- Power on the unit and verify that the status LED indicates normal operation. Check sensor readings on the optional display or via connected software.
-
- Perform regular calibration annually using standard temperature sources to maintain accuracy.
-
- Inspect wiring connections quarterly for tightness and signs of corrosion. Clean the unit’s exterior with a dry cloth to remove dust.
System Introduction
The CCC TMPU-1002 functions as a critical temperature data acquisition node within industrial control systems, integrating with three key layers:
- Sensor Layer: Interfaces with thermocouples or RTDs installed on equipment (e.g., motors, furnaces, pipelines) to capture raw temperature signals.
- Processing Layer: Conditions incoming signals (filtering, amplification) and converts them to digital values via high-precision ADCs. The microprocessor processes data, applies linearization, and computes accurate temperature readings.
- Communication and Control Layer: Transmits processed data to SCADA, DCS, or PLC systems via Modbus protocols. Analog outputs provide real-time temperature signals for closed-loop control, while digital outputs trigger alarms or safety actions when thresholds are exceeded.
In a typical application, such as a chemical reactor system, the TMPU-1002 monitors multiple zones of the reactor vessel. It sends temperature data to a PLC, which adjusts heating or cooling systems via the unit’s analog outputs. If temperatures exceed safe limits, digital outputs activate shutdown mechanisms, preventing equipment damage.
