Description
ISOS 4-20mA-E adopts Sunyuan's unique electromagnetic isolation coupling and high-efficiency loop stealing invention technology, so that the IC does not need independent power supply. The two-wire loop power supply output mode can save the auxiliary power supply and the two power lines, which greatly simplifies the user's design and reduces the user wiring cost. The IC includes a current signal modulation and demodulation circuit, a signal coupling isolation conversion circuit,  The small input equivalent resistance enables the IC to collect the current signal voltage from the sensor output loop to an ultra-wide range (5~32VDC), so that the user can realize long-distance, distortion-free transmission without external auxiliary power supply.
 
The ISOS 4-20mA-E output is designed for a two-wire power supply circuit in series with 24VDC and sampling resistors (two-wire instruments). It is also used with analog input interface boards (host computers), PLCs, DCS or other commonly used in industrial fields. The meter has an analog input port that matches the active load. The product can meet the harsh environment requirements of industrial grade wide temperature, humidity and vibration. It is very convenient to use. It only needs to connect a 2KΩ multi-turn potentiometer for ADJ correction, which can realize the isolation and transmission of the two-wire 4-20mA signal. Acquisition control. The products are IC package mounted on the PCB, DIN35 standard rail installation and PIM panel embedded installation. The DIN rail type installation can realize multi-channel isolation transmission functions such as one-in-one-out, two-in and two-out, three-in and three-out, and the PIM panel embedded intelligent transmission table can realize 4-20mA signal isolation display and alarm control. A wide range of functions such as long-distance distortion-free transmission. Widely used in metallurgical mining, petrochemical, power equipment, medical equipment, industrial automation, new energy facilities and military research, users can choose the right products according to the needs of the site.
