Din 3x3 Iso 4-20ma-e - Small Size, 83x51x37mm, Green Color | High Precision 4-20ma Signal Isolation, Two-wire Loop Power Supply Output, 3kv Isolation, 2-year Warranty

Small size, low cost, high precision standard DIN35 rail mounted multi channel two wire 4-20mA analog isolation controller converts input active 4-20mA current signal into isolated passive control signal output, controlling two lines Power supply (explosion-proof mode) 4-20mA current loop. The sensor signal acquisition and the analog input interface active load are matched, which effectively solves the problem of collecting the active 4-20 mA current signal and the power supply conflict of the two-wire current loop power supply receiving port.

DIN (1X1 / 2X2 / 3X3) ISO 4-20mA-E uses high-performance loop stealing technology to eliminate the need for a separate power supply. The two-wire loop power supply output mode can save two power lines, greatly simplifying the user's design and reducing the user wiring cost. The product internally includes a current signal modulation and demodulation circuit, a signal coupling isolation conversion circuit, and the like. The small input equivalent resistance enables the isolated controller to collect the current signal voltage from the sensor output loop to an ultra-wide range (5~32VDC), so that the user can realize the signal long distance without external auxiliary power supply. The need for distortion transmission.

DIN (1X1 / 2X2 / 3X3) ISO 4-20mA-E output is designed for the two-wire power supply circuit of 24VDC and sampling resistor (two-wire instrument) in series with the analog input interface board commonly used in industrial fields (upper position) Machine, PLC, DCS or other instrument that matches the analog input port of the active load. The product can meet the requirements of industrial grade wide temperature, humidity and vibration in the harsh environment. It is very convenient to use. It only needs external 10KIC multi-turn potentiometer for ADJ correction, which can realize the isolation and transmission of the three-way two-wire 4-20mA signal. And acquisition control.
