IProduct SeriesIDBThe distributor provides power to various two-wire transmitters and also sends current signals from the transmitters（4-20mA DC）Convert to a voltage signal isolated from it（1-5V DC）As an output. existIIn the series,ISBA safety barrier is a necessary safety barrier for constructing an intrinsic safety explosion-proof system. It is connected to intrinsic safety instruments installed in explosive hazardous areas (sites) to limit current and voltage. Ensure that electrical energy sufficient to cause an explosion does not enter hazardous areas.ITEtemperature/Voltage transmitter is a direct current transmittermVConvert the resistance change signals of signals, thermocouples, thermistors, and sliding line resistors into isolated ones1-5V DCThe unified signal. When measuring temperature, a linearizer is attached to establish a linear relationship between temperature and input.
