Level Converter V5.0

Product description

The Level Converter V5.0 is an interface converter that converts RS232 signals from a PC into the signal levels required for K-Line or RS485. Thanks to galvanic isolation of at least 1 kV, the PC hardware is reliably protected against malfunctions on the device under test (DUT). Available in two variants – a K-Line version and an RS485 version – in a rugged housing, the Level Converter V5.0 can be used flexibly in a wide range of applications.

Technical description

The device precisely converts RS232 signals to the specific requirements of K-Line or RS485 communication:

K-Line: A bidirectional single-wire bus used primarily in the automotive industry for diagnostics and control (ISO 9141, ISO 14230-1).

RS485: A differential serial interface that excels in industrial applications thanks to its high noise immunity and suitability for long transmission distances.

The integrated galvanic isolation prevents unwanted voltage transfer and minimizes interference, ensuring stable and secure data exchange.

Technical specifications (selection)

• Supply voltage: 6 V to 24 V
• Galvanic isolation: At least 1 kV
• Interfaces:
• RS232 (PC side)
• K-Line (bidirectional single-wire bus)

• RS485: Standard 1 MBaud, tested up to approx. 3 MBaud

Connection options: Configurable jumpers and alternative supply variants allow flexible integration.

(Detailed connection information and further technical details can be found in the data sheet.)

Applications

Automotive industry: Use in diagnostic devices and communication systems based on K-Line.

Industrial applications: Reliable data transmission in environments prone to interference, ideal for automation technology and control unit development.

Research and development: Efficient test and prototyping solutions for interface conversion and communication projects.

The Level Converter V5.0 thus offers a flexible, robust and safe solution for converting RS232 signals into K-Line or RS485 signals – ideal for demanding industrial and automotive applications.
