The DFM105 Tachometer is a more versatile version of the DFM100. It is fitted with the DFM125 software but does not have a front panel keypad. Programmed by a plug-in keypad from the rear of the tachometer, it has the full DFM125 capabilities.

Fixed or floating decimal point operation can be selected and programmable features include display, scaling, variable update rate, integer mode, display average and readout precision. Output options include dual relays or 0-10V & 4/20mA signals.

• Large 14 mm bright LED display with fixed or floating decimal point.
• Readout in RPM or engineering Units to suit most applications.
• Front panel LED for sensor operation, alarm levels and x 1K display reading.
• Simple programming via optional rear plug-in keypad.
• Variable update time for fast or slow response requirements.
• Display averaging function for fluctuating measurement situations.
