RSF Elektronik: Digital Readout (Z 300 Series)

Measurement Readout

For a comfortable issue of measured values RSF Elektronik offers PC interface cards, subdividing electronics as well as the new relaunched digital readout Z 300. Z 300 replaces the legacy model of the Z 7xx series.

The Digital Readout Z 300 is especially suited for use on milling, drilling and boring machines and lathes with up to three axes. A separate I/O unit provides switching inputs/outputs for simple tasks in automation (optional accessory: IFB 48).


The Z 300 display unit is designed as a sturdy upright unit with splash-proof full travel keypad for use in a workshop. It is equipped with a monochrome flat screen for position values, dialog and input displays, graphic functions and graphic positioning support.

Data Interfaces

The Z 300 features an RS-232-C/V.24 serial interface for measured value transfer to a PC or printer, for input/output of parameters and compensation value lists and for dialogs.


Z 300 is basically conceived as an upright unit. Mounting possibilities:

  • Threaded mounting holes M6 and M8 on the housing floor

  • Mounting frame (optional, ID 532 811-01) for mounting the digital readout in a housing or operating panel

Technical Data:


  • Axes: 2 or 3

  • Encoder Inputs: RS-422 inputs for quadrature signals and reference pulse

  • Display: 5.7 " monochrome flat-panel display for position values, dialogs and inputs, softkeys

  • Status display: Tool, reference point, operating function, feed rate, ABS/INC, mm/inch, stopwatch
