Universal input, can be used in conjunction with various sensors and transmitters to achieve measurement, display, and public alarm control of six physical quantities such as temperature, humidity, pressure, liquid level, and flow rate; Data can be uploaded to the computer through a serial communication port; The dual 4-digit high brightness LED digital display window can display two signals simultaneously or switch to display six input signals separately. We can provide 96x48mm panel products with a compact structure.
Technical Parameter
Input specifications:
Thermocouples: K, S, R, n, E, J, T, Wr5-26, WR3-25, B, EA1, EU2, etc
Thermistors: Pt100, Cu50, Cu53, bA1, BA2, etc
Resistance: 0-80 Ω, 0-400 Ω (when the resistance input is a three wire wiring method, it is required that the three wire resistance is equal and the lead resistance is less than 18 Ω), etc
Voltage: 0~20mV, 0~60mV, 0~100mV, 0~1V, 0.2~1V (input impedance ≥ 500k Ω)
Current: 0-10mA (input resistance ≤ 500 Ω), 4-20mA, 0-20mA, etc. (input resistance ≤ 250 Ω)
Measurement range: -1999~+9999
Measurement accuracy: Level 0.5.
Response time: ≤ 0.5 seconds
Alarm function: Each circuit is equipped with two independent alarm points, and the alarm mode can be set.
Alarm output: Relay contact switch output (normally open+normally closed), contact capacity 220VAC/2A or 24VDC/2A. When the relay contacts are connected to an inductive load, the two ends of the load must be connected to a spark absorption circuit, and the carrying capacity is correspondingly reduced.
Alarm accuracy: ± 1 ℃ or ± 1 defined unit.
Communication interface: RS485, RS232 serial communication interface, can be connected to an external micro printer.
Usage environment: ambient temperature of 0-50 ℃; Relative humidity: ≤ 85%, avoid strong corrosive gases.
Power supply: Switching power supply 100~240vac (50Hz/60Hz); Switching power supply 24VDC ± 2V.
Power consumption: ≤ 4W.
