Input & Measurement Parameters: It has 6 thermocouple input channels and 1 cold junction channel, supporting multiple thermocouple types including B, E, J, K, R, S, T, N, and C. The temperature measurement range spans from -200°C to 1760°C, with 16 – bit resolution and a measurement accuracy of ±0.1% of the reading plus ±0.5°C. The module update rate for all channels is 50 milliseconds, and the settling time to 5% of full scale is less than 80 milliseconds.
Electrical Parameters: It uses a 24VDC power supply, with a maximum power dissipation of 4.3W. The input current is 250mA under 5.1VDC and 125mA under 24VDC. The input and output have an electrical isolation of 1500V AC. The common mode rejection is 120dB at 60Hz and 100dB at 50Hz, while the normal mode noise rejection is 60dB at 60Hz.
Physical Parameters: Its dimensions are 3.7 x 2.2 x 1.2 inches, and the weight is 0.5 pounds. The compact size allows it to be easily installed in various control cabinets with limited space, facilitating integration into the overall industrial control system. It adopts a TC – TBN H 20 – position terminal block for wiring connection.
Environmental Parameters: It can operate stably in an ambient temperature range of -40°C to 70°C, and the storage temperature range is -40°C to 85°C. It can work normally in an environment with 5% – 95% non – condensing relative humidity and has an IP65 protection level, which can resist the impact of harsh industrial environments such as dust and water splashes.
Wide Compatibility and High – Precision Measurement: It supports multiple mainstream thermocouple types, enabling flexible matching with different temperature detection equipment in industrial sites. The 16 – bit high resolution and excellent measurement accuracy ensure that it can capture tiny temperature changes in the production process and output reliable and accurate temperature data.
Strong Anti – interference Capability: The high common mode and normal mode noise rejection capabilities can effectively filter out electromagnetic interference from the industrial on – site power supply and other electrical equipment. The galvanic isolation design between channels further avoids signal mutual interference between different input channels, ensuring the stability and integrity of temperature signal transmission.
Fast Response and Real – time Monitoring: With a 50 – millisecond full – channel update rate and a short settling time, it can quickly respond to temperature changes in the measured object. It can realize real – time monitoring of the temperature of key equipment and processes in industrial production, and timely feed back abnormal temperature information.
Open Circuit Detection Function: It is equipped with an open thermocouple detection function, and the typical detection time for an upscale reading is 5 seconds. This function can promptly detect faults such as thermocouple disconnection, helping maintenance personnel find and handle problems in a timely manner to avoid production risks caused by invalid temperature data.
