Intelligent Digital / Bargraph Display Controller uses advanced intelligent microprocessor controlled for temperature, humidity, pressure, level, flow rate, speed and other physical quantity detection signal display and control, and to a variety of nonlinear linear input signal correction precision measurements. Using recent technology without the jumper, the input port with single and universal signal input function, you only need a simple menu selection through the instrument, you can achieve a variety of input signals (various thermocouple, RTD, standard voltage / current standard signal) to easily switch between, improve the instrument's versatility and reliability. Using high-brightness LED digital display and high-resolution beam display (shown to scale), the measurement / control value display more clear and intuitive. Input and output circuits are optically isolated, anti-interference ability. Available with serial communication interface with a variety of devices with a serial interface for two-way communication, a network control system. With a variety of standard dimensions, can be applied to a variety of measurement and control applications. Machine using Snap structure, making installation very simple. The main technical parameters of the input signal: Analog · thermocouple: standard thermocouple-B, S, K, E, J, T, N, R, WRe3 ~ 25 etc. · Resistance: Standard RTD-Pt100, Cu50, Cu100 remote Pressure resistance -30 ~ 350Ω etc. · Current: 0 ~ 10mA, 0 ~ 20mA, 4mA ~ 20mA, etc. (input resistance ≤ 250Ω) · Voltage: 0 ~ 5V, 1V ~ 5V, mV, etc. (input impedance ≥ 250KΩ) Pulse · waveforms: square wave, sine wave, triangle wave · Range: greater than 4V (or according to user requirements) · Range: 0 ~ 5KHz (or according to user requirements)
