Function

This signal conditioner provides the galvanic isolation between field circuits and control circuits.

The device repeats the input signal from a control system to drive SMART I/P converters, electrical valves, and positioners located on the field side.

Digital signals are superimposed on the analog values at the field side or control side and are transferred bi-directionally.

The current is transferred via a DC/DC converter and repeated at the output terminals.

An open field circuit presents a high impedance to the control side to allow alarm conditions to be monitored by the control system.

Test sockets for the connection of HART communicators are integrated into the terminals of the device. 

Intrinsic Safety Isolated Barriers

Intrinsic safety barriers from Pepperl+Fuchs limit the energy that is supplied to a circuit and protect hazardous areas from excess energy. By limiting energy to a safe level, intrinsically safe circuits prevent the ignition of potentially explosive atmospheres.

In addition to their explosion protection function, isolated barriers offer galvanic isolation to protect measurement and control circuits from signal distortion and dangerous surges. These interface modules also convert, standardize, and split measurement and control signals.

Isolated Barriers of the K-System

Solving a wide range of applications in one system, the Pepperl+Fuchs' K-System guarantees a reliable and economical signal transmission between your field device and the control system. Whether your plans include a single isolating module or a large scale system integration—application-oriented solutions characterize the entire K-System product range.

Here are just some of its unique features:

Product Portfolio

K-System offers an extensive range of intrinsic safety interface modules for many signals and applications - from simple isolators to highly functional modules.

Power Rail

The Power Rail is an insert in the standard 35mm DIN rail. When mounting on the DIN rail, the units are simply snapped in place. The Power Rail supplies the modules with power and provides a path for the collective error message from individual isolators. Power Rail reduces wiring and maintenance costs because it eliminates the need to daisy chain the wires. It also simplifies expansion. Just snap in a new module when you're ready to add to your system.

Power Feed Modules

The supply voltage is coupled to the Power Rail via the power feed modules. A built-in fuse provides effective group protection for the plugged-in modules. A line fault detected by the interface module is output via the potential-free contact of the power feed module.

Easy Configuration

With the powerfil software tool PACTware, project documentation is easier to create, and highly functional interface modules are easily configured.
