ISOS V-4-20mAPressure sensor circuit feeding type signal transmitterThe IC is designed as a low-cost, small-sized standard SIP7 Pin flame retardant package that can be directly soldered onto PCB circuit boards. The signal transmission IC contains signal modulation and demodulation circuits, signal coupling isolation transmission circuits, high isolation DC-DC boost circuits, V/I conversion circuits, etc. The output circuit has a wide voltage range (12V-36VDC), high conversion accuracy, and good linearity.

The design and use of signal transmission IC is very convenient. Customers only need to add a small number of peripheral devices at the input end to achieve voltage signal distribution for pressure sensors, displacement potentiometers, and other sensors and bridge (weighing) detection circuits that require power distribution. The integration process and new technology isolation measures inside the IC enable the device to meet the requirements of 3KVDC insulation voltage and industrial grade wide temperature, humidity, and vibration in harsh on-site environments. The product has a small size and is easy to install. It can be embedded inside the sensor to directly convert pressure, displacement, and angle resistance signals into standard 4-20mA signals. The full and zero points can be adjusted and calibrated by the user through an external potentiometer.
