Model ACFM Analog to Frequency Converter Module

Brand: Red Lion Controls

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.
Features

  • 3-way isolation of input/output signals
  • Universal conversion module - inputs and outputs selected via DIP switch settings
  • Ultra slim design only 0.244" wide
  • 19-30 Vdc power
