For safe environments

For mixed Ex i and non-Ex i signal circuits, users can draw upon the advantages of the ISpac isolator system. While existing modules have served to connect intrinsically safe field devices to the control level, isolators are now also available for segments that are not suitable for intrinsically safe wiring. Of course, field devices which cannot be connected to intrinsically safe networks can be connected directly to a PLC or control system. In industrial environments, however, data transmission can be then disrupted by interference. Galvanic three-way isolators such as ISpac devices counteract these influences, ensuring a safer and more precise signal communication. The ISpac product range for non-Ex i applications covers a wide functional range, including transmitter supply units, isolating repeaters for 0/4…20 mA signals, loop-powered isolating repeaters for 0/4…20 mA signals, temperature transmitters for common sensors and limit monitors for temperature sensors, 0/4…20 mA signals or frequency signals. An integrated error alert function enables users to quickly isolate malfunctions that occur. Like all ISpac isolators, they were tested by an independent laboratory and have been approved for zone 2 installation.
