The UNICONT PGK-301 Ex DIN rail mountable intrinsically safe isolator and power supply modules are suitable for providing power supply for 2-wire transmitters operating in hazardous applications, as well for isolating the input, output and supply voltage galvanically. Moreover the device perform high accuracy signal transmission between Ex and non-Ex areas. The data transmission can be 4-20/4-20 mA or 2-way digital HART depending on model type. The UNICONT PGK-301 Ex intrinsically safe isolators perform signal transmission to the non-Ex Zone with microprocessor controlled digital sign-processing which provides high transmission accuracy. This is a special demand in case of certified, high precision (for example magnetostrictive) transmitters. If fast conversion speed is necessary, the high speed types are recommended. The number of connectable transmitters is determined by the intrinsically safe limit data!
