4-Channel Thermocouple Indicator Scanner Used With Recorder
Multi-Channel indicator----AI-702M/704M/706M panel
Suitable for indication, alarm and retransmission of temperature, pressure, flow, level humidity etc.
0.2% accuracy. Programmable and modular inputs like J0,J1,J2,J3,J4,J5 selectable.
Provides 1-2, 1-4, 1-6 channels of independent process indications, Support RS485 communication to PC or AI True-color HMI Touch Screen/Split Paperless Recorder.
With a built-in wet-and-dry bulb temperature algorithm; subject to the setting wind speed and atmospheric pressure constant to import dry-bulb and wet-bulb Pt100 signal for precisely measuring surrounding temperature and humidity. Maximum two independent transmission output.
