10KVAC High Isolation Two Wire Passive Voltage to 4-20mA Signal Transmitters
SunYuan ISOH V-4-20mA is the newly developed 10KVAC highest isolation voltage, small size (16 pin single line SIP16 Pin) low-cost passive two-wire sensor voltage signal to 4-20mA isolated transmitter module in the industry . The module can provide a set of 5V (3mA) function expansion power supply to the input circuit and supply power to the pre-stage circuit through the post current current loop feeding mode, and receive the voltage signal from the output of the pre-stage circuit, and output 4~20mA after isolation conversion. Standard two-wire current signal. The new product can realize high precision, high linearity 10KV anti EMC high isolation transmission and VI conversion between industrial field passive two-wire voltage sensor and instrumentation/PLC/DCS.
ISOH V-4-20mA product is designed as a low cost, small size, standard SIP16 Pin flame-retardant IC package that includes a signal modulation and demodulation circuit, a signal coupled isolation converter circuit and a VI conversion circuit. The product has the characteristics of wide output voltage range (12-36VDC), high conversion precision and good linearity. It is very convenient to use. Customers only need to add a small number of peripheral devices at the input end of the product to realize the distribution of voltage signals in the sensor and bridge (weighing) detection circuit of the electronic scale, displacement, potentiometer, etc. The product is small size and easy to install. It can be placed inside the sensor to directly convert the displacement and angular displacement resistance signals into a standard 4-20mA signal output. The full scale and zero point can be adjusted and calibrated by the user through an external potentiometer. The advanced integrated process structure and new technology isolation measures enable the device to achieve high signal isolation of 10,000 VAC.
ISOH V-4-20mA series new products enable analog voltage signals from industrial field sensors and signals between instrumentation, PLC and DCS, high-precision, high linearity 10KV anti EMC high-isolation transmission and VI conversion. Products include IC package and DIN35 Rail-mounted packaging. It is widely used in track voltage monitoring, generator or motor safe operation monitoring, power transmission and distribution remote monitoring, instrumentation and sensor signal transceiver, medical equipment safety barrier, industrial automation control. nuclear power equipment and other fields etc.
