6.Low cost and small size non-isolated two-wire 4-20mA analog quantity acquisition and conditioner SY 4-20mA-P series
SY 4-20mA-P is a non-isolated two-wire 4-20mA analog signal acquisition and conditioner chip with low-cost design. It belongs to the SY 4-20mA series of products. It can convert the input active 4-20mA current signal into a passive control signal output, and control the two-wire power supply (explosion-proof method) 4-20mA current loop. The sensor signal acquisition is matched with the active load of the analog input and output interface, which effectively solves the problem of the power conflict between the acquisition of the active 4-20mA current signal and the receiving port of the two-wire current loop power supply loop.
