1、 Overview
The XMT-4000 series intelligent temperature and humidity display controller is suitable for measuring, displaying, and controlling temperature and relative humidity in the air, mainly used in industries such as pharmaceuticals, warehousing, and textiles.
2、 Main performance and indicators
1. Temperature input: Thermistor: Pt100 Standard signal: 4~20mA
2. Humidity input: Standard signal: 4~20mA
3. Input characteristics: The input impedance of the thermistor is ≥ 10K Ω, and the three leads are equal,
Current input impedance ≤ 250 Ω
4. Zero point and magnification automatic tracking for long-term operation without drift
5. Using non-volatile memory for power failure protection, parameters can be reliably stored for a long time
6. All parameters and configurations of the instrument are set and inputted through several operation keys on the panel
7. Constant current power output: DC24V, Used in conjunction with temperature and humidity sensors
8. Installation method: disk mounted
9. Display mode: The main screen displays temperature with a 4-digit LED digital tube, and the auxiliary screen displays humidity with a 4-digit LED digital tube
10. Accuracy level: Instrument display level ± 0.5 ± 1d; Resolution: Last 1d.
11. Input alarm method:; Each has 2 alarms (upper limit, upper limit, lower limit, lower limit)
Choose any working mode (alarm below or above the set point) and select any deviation. Output contact capacity AC220V, 3A non inductive load.
12. Analog transmission output: 1 transmission output, output status can be set according to user needs; In addition, it can be equipped with isolated output according to user needs. Output impedance DC4~20mA, load below 500 Ω; DC0-10mA load below 1K Ω.
13. Insulation strength: There should be no breakdown or arcing phenomenon after 1 minute of AC1000V input.
