Designed to limit the electrical energy supplied to the hazardous area. They provide interfacing of equipment placed in the explosion-proof zone with devices and appliances installed in hazardous areas as separating elements between intrinsically safe and intrinsically hazardous circuits.
The barriers are designed to be placed outside the hazardous area. Application options: transmission of unified current signals 0...5, 4...20, 0...20 mA; conversion of unified current signals 0...5, 4...20, 0....20 mA; conversion of unified current signals into 15 V signal; connection of devices with input control unified current signal; connection of load cells; connection of vibration sensors; connection of sensors with output frequency signals; connection of sensors with "dry contact" type output; connection of sensors with discrete signal according to NAMUR standard; transmission of thermocouple signals; connection of thermal resistors; connection of sensor power supply; connection of electromagnetic valves (solenoids); connection of indicators.
