Interface Box IFU 2.1 - Discontinued

The interface box IFU 2.1 allows highly precise analog acquisition of data and control of 3rd party modules over analog and relay outputs. The IFU 2.1 is required only, if the respective instrument can not be controlled or data recorded by the KNAUER software directly (digital I/O). The IFU 2.1 provides 4-channel input/output. It supports high speed chromatography at sample rates of up to 50 Hz if channel one is used exclusively. It can be used with every KNAUER product. The IFU 2.1 is connected via an USB cable to a computer. The power supply is realized through the USB 2.0 connection, which makes a power supply unit obsolete.
