Signal type: Supports B, E, J, K, L, N, R, S, and T type thermocouples, compatible with millivolt signals (-75mV to +100mV).

Resolution: 15 bits + symbol bits, measurement accuracy ±0.1% (full scale).

Sampling characteristics: Single-channel sampling time of 50ms, multi-channel automatic cyclic sampling.

Compensation method: Supports internal cold terminal compensation, and external cold terminal compensation (through compensation wires) is optional.

Power supply and power consumption: DC 24V power supply, typical power consumption 3W, maximum current consumption 150mA.

Isolation level: Electrical isolation between channels and between channels and the backplane bus, with an isolation voltage of 500V DC.

Environmental adaptability: Operating temperature 0°C to 60°C, storage temperature -25 °C to +65°C, protection grade IP20.

Product function

Thermocouple signal acquisition: Accurately convert the millivolt-level signals output by thermocouples into digital signals, suitable for various temperature measurement scenarios.

Cold junction compensation: An internal high-precision temperature sensor is built in to achieve internal cold junction compensation, reducing the influence of ambient temperature on the measurement.

Anti-interference design: By means of electrical isolation and filtering circuits, the signal stability in industrial strong electromagnetic environments is enhanced.

Fault diagnosis: Equipped with channel-level diagnostic functions, it can detect faults such as open circuits and short circuits, and prompt fault information through LED indicator lights and the PLC system.

Flexible adaptation: Supports seamless compatibility with S7-300 series cpus, and parameters can be easily configured through STEP 7 or TIA Portal software.

Application scenarios

Industrial temperature monitoring: Temperature detection of industrial furnaces and kilns in the metallurgy, ceramics, and glass industries, with real-time feedback of temperature data inside the furnaces.

Chemical process control: Temperature monitoring of chemical reaction vessels, distillation columns, and pipelines, in conjunction with PLC to achieve closed-loop temperature control, ensuring reaction stability.

Food and Pharmaceuticals: Temperature monitoring for pharmaceutical fermentation tanks and food processing equipment, meeting the industry's strict requirements for temperature accuracy and stability.

Energy and power: Temperature measurement of key parts of equipment such as boilers and steam turbines, providing data support for the safe operation of the equipment.

Automobile manufacturing: Temperature monitoring of painting production lines and welding equipment to ensure that process parameters meet standards and improve product quality.
