Phoenix Contact MCR-f-UI-DC Manual

MCR-f-UI-DC
Programmable Universal Frequency
Transducer
1. Brief Description
– Frequencies from 0.1 Hz...120 kHz
– Analog inputs selectable between 0-10 V or
0-20 mA
– Analog output and switching output
– 3-way isolation
– Programmable using membrane keypad
– Configuration via MCR/PI-CONF-WIN
– Display of the input or output signal
The new MCR-f-UI-DC is a frequency module that
accepts frequencies between 0.1 Hz and 120 kHz.
The input frequency can be easily selected within this
range and is displayed on the front face of the module.
All common frequency signals (2, 3, and 4-wire) can
be accepted on the input side The input options are as
follows
NAMUR sensors
Frequency generators
Dry contacts
Incremental encoder signals
The input pulses are evaluated by a period measure-
ment, and the output is processed according to the lo-
wer measuring range value and the upper measuring
range value into an analog voltage or current signal.
The module features 3-way isolation between signal in-
put, signal output, and supply to prevent any ground
loop errors.

In addition to the analog output a transistor switching
output, e.g. for alarm processing, is available. The input
frequencies (lower and upper range) can be program-
med in, using the membrane keypad, as revolutions
per minute (rpm) or as Hz. Analog voltage and current
inputs can also be converted and isolated. The LC dis-
play can show both input and output measurement va-
lues.
