德国Motrona传感器UF251: Signal Converter Analogue (V, I) to Frequency and
to Serial RS232 / RS485
High performance analogue-to-frequency and analogue-to-serial converter
Input range:-10V...+10V / 0/4...20mA
Conversion time approx. 1ms only
Quadrature frequency outputs HTL (A/B/Z) from 1 Hz to 100 kHz and
TTL differential / RS422 (A,/A, B,/B, Z,/Z) from 1 Hz to 500 kHz
Phase A/B depending on polarity of input signal, marker pulse output with programmable distance.
Various user modes: Programmable V / f characteristics, Motorized potentiometer function, cyclic frequency output curves etc.
RS232 and RS485 interface for serial readout of the conversion result and other internal registers
Adjustable floating average filter as well as operator programmable linearization curves
Printer mode for automatic data transfer of internal registers to a data logger or PC
For 115/230 VAC supply see accessories
