Introduction:

Sunyuan Small size, low cost, high precision standard DIN Rail 35 Two-wire Passive Sensor Signal Isolated Distributor IC is a kind of signal modules with electro-magnetic hybrid integrated circuits inside. There are signal interference suppression circuit, signal modulation circuit, signal isolation circuit and output demodulation filtering circuit in the IC. By employing internal isolation technique, proper I/O side creepage distance, the isolated voltage of that signal transmitter is up to 3000VDC. DIN3 ISO 4-20mA-F Loop Powered Distributor can transmit 4-20mA signal from PLC, DCS, PCC and other controlling system to sensors or intelligent meters to facilitate the isolation, measuring and long-distance transmission of two-wire passive sensors. The isolated distributor is designed on the basis of two-wire loop powered (explosion-proof) circuit which has serial connection on 24VDC and sample resistance (load resistance). It can operate well with analog input interface board (host machine), PLC, DCS and other meters and instruments with analog input interfaces. The two-wire 4-20mA loop powered distributor is easy to achieve two-wire sensor signal isolation, transmission and power distribution without external components and auxiliary power supply.
