The Solution to most Applications with Speed, or Flowrate, or any other Variable transmitted as Frequency

Superior by these Common Advantages

• Precise adaption to the application, by easy programming. Fast and safe access to parameters. 5 digits factors. Display reads the variable Parameters protected against loss.
• Two input paths accept sensors and transmitters with high and low signal level.
• Total measuring range 0...100kHz.
• Pulse interval measuring principle with floating period automatics combines fast response and programmable averaging for stable operation.
• Input pre-divider compensates periodic pulse distance fluctuation (with D421 only).
• Wide supply range: 18...40 volts AC/DC or 85...265 volts AC/DC.
  

Series C/D/E124 Multi-Purpose Versions with one or two Channels as Panel Mount, Snap-on-Track, or 19-inch module, performing these Function: 124.1 2 independent measuring channels, with selection to absolutes, ratio, difference, eith display, analog output, setpoint alarms. 124.1S2 1 input to speed/direction sensor A5S30...33, with direction signal contact, speed setpoint contact, analog output, display 124.1S3 1 input to speed sensor, other to accept binary signal to select 1 of 32 predetermined adaption factors, with display and setpoint contacts. 124.1S5 Linearization by 21 coordinates in both inputs, with display and setpoint contacts. 124.1S6 single channel unit for speed, also determining the acceleration rate, with display, analog output and 2 alarms.
