EX Safety Barriers
Ex Safety Barriers (Ex Isolation Amplifiers) transmit switching operations from an intrinsically safe control circuit to a non-intrinsically safe active current circuit. They prevent electrical conduction between the two circuits via galvanic separation and thus protect your electrical circuits in potentially flammable and hazardous areas.
Advantages of EX safety barriers
Flexibility and simple use
EX safety barriers will impress you with their flexibility and simple use, as they have only two terminals for the power supply (both AC and DC).
Simple and error-free installation
The EX Isolation Amplifiers feature removable terminals to simplify the design, conversion and maintenance of installations. This allows you to install the devices easier, prevents wiring errors when replacing them, and provides reduction of mounting and associated costs.
The devices with screw and cage clamp terminals are available. The male connectors are coded to prevent the incorrect connection.
High packing density
Different EX Safety Barriers series that provide the isolation, conditioning, processing, conversion and matching of digital and analog signals, feature a compact, space saving design. As these slim and multichannel devices can be mounted directly next to each other, this saves space in your control cabinet without any loss in the level of user‑friendliness and reliability.
Flexible mounting
The EX Safety Barriers series are designed for snap‑on mounting on DIN rails but you can also fasten them on a mounting plate with screws. The devices can be mounted vertically or horizontally.
Different operating concepts
To allow an easy handling in your daily routine tasks, EX isolation amplifiers should have precisely the range of functions that you require for your application. In order to meet all requirements in terms of handling, commissioning and diagnostics, our wide portfolio offers a selection of different operating concepts, suitably packaged in the required design. From the compact variants to teachable devices with intuitive menu guidance, to modules with convenient parameter setting and diagnostics, to FDT/DTM technology.
ATEX compliance
All EX Safety Barriers feature intrinsically safe input and output circuits and are approved according to the new framework directive 94/9/EC, regarding equipment and protective systems intended for use in potentially explosive atmospheres.
They can thus be used as associated equipment. Their terminals are designated for connection of intrinsically safe signals.
