Process signal to frequency converter PXF-10

Description

Signal converter for the conversion of an analogue process signal to a pulsating (50% duty cycle) transistor output. A typical application would be to convert an analogue signal from a probe to a pulsating output for input at a digital input of a PLC. Input, output and operating voltage are internally galvanically isolated (3,75kV). Input is selected via switches and output is selected via choice of terminals. See connecting diagram.

Features

- Input 0 - 5V/0 - 10V/-10-+10VDC/0 - 20/4 - 20mA in one version
- 2 standard output versions;
- Output 0-50Hz/0-5kHz/0-10kHz - selected via terminals
- Output 0-40Hz/0-4kHz/0-8kHz - selected via terminals
- Output offset and gain adjustable ±5%
- LED indication of input less that 5% / indication on probe failure
- Operating voltage 24VDC, 24VAC, 115VAC, 230VAC
