MODEL AFCM - ANALOG TO FREQUENCY CONVERTER MODULE
DESCRIPTION
The configurable analog to frequency converter is used to convert analog
standard signals to frequency signals or pulse width modulated (PWM) signals.
Input signal ranges are 0 - 20 mA, 4 - 20 mA, 0 - 10 mA, 2 - 10 mA,
0 - 10 V, 2 - 10 V, 0 - 5 V, or 1 - 5 V.
The DIP switches are accessible on the side of the housing and allow the
following parameters to be configured:
– Input signal
– Output values
– Output type (frequency or PWM)
– Filter type (for smoothing interferences on the input signal)
– Input over/under range fault detection
SAFETY SUMMARY
The device may only be installed and put into operation by qualified personnel.
The corresponding national regulations must be observed.
