ISOBE5600 Isolation System

Transmission system with integrated fiber-optic isolation

The ISOBE5600 isolation system provides an additional isolation for existing measurement systems.

The system comprises a transmitter unit connected by optical fiber to the ISOBE5600r receiver unit. Either the battery-powered ISOBE5600t (high voltage) or the line-fed (mains-fed) ISOBE5600tm (medium voltage) with isolated power supply (1.8 kV isolation) can be used as transmitter. The rechargeable battery of the ISOBE5600t transmitter unit is easily replaceable, and provides energy for twelve hours of continuous operation. A second rechargeable battery (optional) doubles the operating time to 24 hours.

High precision

The transmitter, positioned in close proximity to the test object, performs the signal A/D conversion, and the digital transmission of measurement data via optical fiber. Compared to analog transmission, digital signal transmission provides a significant increase in measurement accuracy; the ISOBE5600 isolation system eliminates signal drift and transmission line noise. The D/A converter in the receiver unit performs the re-conversion of data into analog signals, thereby enabling further processing with conventional measurement technology.

Large bandwidth

The ISOBE5600 isolation system offers nine measurement ranges from ± 100 mV to ± 50 V. The bandwidth of 20 MHz not only covers applications with DC signals or power line (mains) frequencies, but also applications involving high clock-rate switching power supply and motor controls.


Up to four transmitters can be connected via optical fiber to a receiver. Equipped with display and multi-functional dial, the receiver has all the necessary controls to enable the direct and remote set up of installed transmitters for measurement, from a safe distance. The ISOBE5600 isolation system is compatible with data acquisition instruments from HBM as well as other manufacturers.
