Isolated Barriers of the K-System

K-system_isolated_barriers_assembly

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.

    • International Safety Standards

    SIL ratings are available at no extra charge.

    • Easy Configuration

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

isolated barrier - switch amplifier k-system

Switch Amplifiers

Switch amplifiers process digital input signals, amplify them, and initiate switching outputs via relays or transistors.

Applications include limit value monitoring, final position feedback, and position detection of moving parts such as valves. Switch amplifiers also enable 1:1 pulse transmission to the output.

isolated_barrier_frequency_converter k-system

Frequency Converter

Frequency converters convert digital input signals into analog current or voltage signals and evaluate pulse sequences.

These devices are used for rotation speed, standstill, and slip monitoring as well as volume measurement with oval wheel meters.

isolated_barrier_solenoid_driver k-system

Solenoid Drivers

Solenoid drivers transmit digital output signals from the control unit to the valve. In contrast to relay modules, they also provide voltage and current.

They control valves, regulate open/close functions, and can control visual or acoustic indicators.

isolated_barrier_relay_module k-system

Relay Modules

Relay modules transmit digital output signals from the control system to the field device via a relay. The voltage is applied externally.

Applications include signal horns, warning lights, applications with active cooling, galvanic isolation of controls during system modernizations, emergency shutdown valves, and motor controls.

isolated_barrier_transmitter_power_supply k-system

Transmitter Power Supplies

Transmitter power supplies transmit analog input signals from transmitters to the controller and supply voltage via the same line. SMART transmitter power supplies modulate a digital data signal to the 4 … 20 mA signal.

Typical areas of application are the measurement of pressure, temperature, or fill level.

isolated_barrier_repeater k-system

Repeaters

Repeaters amplify and restore signals without changing the signal itself.

Repeaters ensure greater ranges.

isolated_barrier_signal_converter k-system

Signal Converters

Signal converters transmit analog input signals to the controller and convert them into standard signals. They amplify and linearize the sensor signal.

Applications include the use of field devices on control systems, especially for small PLCs that cannot process all sensor signals.

isolated_barrier_trip_amplifier k-system

Trip Amplifiers

Trip amplifiers monitor analog and digital input signals for exceeding or falling below set limit values.

Their switching output activates emergency shutdowns or alarms.

isolated barrier_current driver_k-system

Current Drivers

Current drivers transmit analog output signals from the control side to the field side, typically a 4 … 20 mA signal.

They control positioners, I/P converters, or field displays, for example.
