With a width of just 6,2 mm, the Mini Analog signal converters from Phoenix Contact now include a configurable frequency converter in addition to the isolating amplifiers and temperature transducers. The Mini MCR-SL- UI-f captures typical analog signals ranging from 0(4) mA to 20 mA, 0(2) V to 10 V, and 0(1) V to 5 V and converts them into a frequency signal.
The following frequency ranges are available for selection: 0 kHz to 10 kHz, 0 kHz to 5 kHz, 0 kHz to 1 kHz, 0 Hz to 500 Hz, 0 Hz to 100 Hz, and 0 Hz to 50 Hz. The signal combination is quick and easy to configure via the DIP switch. The advantage of this solution lies in the fact a more cost-effective digital input can be used on the controller in place of an analog one.
A particular feature of the Mini Analog signal converters is their 3-way isolation. The 3-way isolation prevents the different sensor circuits from interfering with one another and improves the quality of the measuring circuit.
The possibility of distributing power via one plug connector provides an uncomplicated and convenient means of supplying power to devices. The mounting-rail bus connector is placed into the mounting rail, in so doing supplying the transducer with power. The reduced installation time and the increased flexibility are major advantages. Individual devices can be easily removed from the rail while operations continue.

Maintenance, Test & Measurement, Calibration
Microdieseling is a pressure-induced thermal degradation mechanism in which entrained air bubbles are compressed so rapidly that the surrounding oil ignites, producing soot, varnish and sludge. WearCheck explains how it happens, why the damage varies, and how oil analysis detects it.
