EX safety barriers supply power to the sensors in a hazardous area, receive a proportional current, convert digital input signals to output signals, amplify them and transfer switching signals to a control device. Signals can be connected up to Zone 0/Div. 1 in order to limit the energy to the field, thereby ensuring no explosion is possible.
As these devices are designed for a voltage range between 20-250 VAC/20-125 VDC, you can connect them to any industrial supply network. This considerably simplifies your device selection, stock‑keeping and spare parts management.
The intrinsic isolation amplifiers offer not only sufficient power reserves and reliable protection against under- and overvoltage, but they also meet explosion protection requirements.
