Product introduction:
Display controller specification
ProtEX series display controller table:
5 figures, 0.7 "above"
7 - bit characters show that the word is 0.4 "less than"
SafeTouch touch key programming
Explosion-proof, protection IP65 (NEMA 4X)
Special support can be selected for wall or pipe installation
Operating temperature: -40-75 C
Input specifications: thermocouples: K, S, Wr, E, J, T, B, N and so on.
Thermal resistance: Pt100, Cu50 and so on.
Resistance: 0~80, 0~400, etc.
Voltage: 0 to 20mV... 0 ~ 1V, the input impedance is greater than or equal to 5M, 0 ~ 5V, the input impedance is greater than or equal to 100K.
Current: 4 ~ 20mA, 0 ~ 20mA, the input resistance is less than or equal to 250, 0 to 10mA, the input resistance is less than or equal to 500.
The range of measurement: -1999 to +9999.
Accuracy of measurement: 0.2 (+ 0.2%FS).
Note: the display controller can measure the B indexing thermocouple in the range of 0~600 degrees, but the measurement accuracy can not reach 0.2 level. It can guarantee the 0.2 level measurement accuracy within 600~1800 degrees. Because the precision and consistency of the tungsten rhenium thermocouple itself is low, the measuring precision of the display controller to WRe3-WRe25 is only 0.5.
Alarm output: relay contact switch output (often open + normally closed), contact capacity 220VAC/2A or 24VDC/2A.
Alarm accuracy: a unit of 1 or + 1.
The changing range: 0 to 22mA, 0 to 10VDC.
Transmission precision: 0.3 (+ 0.3%FS).
Communication interface: RS485 serial communication interface and RS232C serial communication interface.
Distribution output: 24VDC voltage, the maximum output current of 25mA, can be used by passive transmitter.
Temperature compensation: -199.9 ~ 200 c digital temperature automatic compensation.
The use of the environment: the environment temperature is 0 ~ 50 degrees, relative humidity is less than 85%, to avoid the corrosive gas.
Power supply: switching power supply 90 ~ 260VAC (50HZ/60HZ), 24VDC + 2V, power consumption is less than 5W.
Display controller weight: less than 1000g.
