Description
Introduction  
    SY 4-20mA-P is a kind of two-wire 4-20mA analog signal acquisition&conditioning IC. It contains internal signal acquisition, conditioning and coupled conversion circuits. A very small input equivalent resistance makes this circuit achieve ultra-wide range (7.5 ~ 32V) voltage input which acquires from sensor signal loop. It can meet the users’ requirements that achieve the signal long-distance transmission without distortion. The 4-20ma loop feed output designed is correspond to 2-wire loop powered in serial connection between 24VDC and sampling resistance (load resistance), and it can be well matched with analog input interface board (upper machine), PLC, DCS, and analog input terminals of other commonly used meters&instruments. And the conditioner module can meet the temperature, humidity, vibration and other harsh industrial on-site environmental requirements. SY 4-20mA-P product is very easy to use. Just by adding a 2KΩ to the multi-turn potentiometer ADJ to do adjustment, user can achieve the two-wire 4-20mA signal transmission.
