AD-FM 210 GS


The frequency converter AD-FM 210 GS is adapted ex works for user-side sensors and delivered exactly calibrated for the application. He can supply an initiator or a contact. Default switching thresholds are set for active signals. The required data must be given when ordering the device. The input pulse train is converted into a proportional impressed analog signal. The output signal is independent of the connected load up to a maximum value.

AD-FM 210 GS


The main area of application is flow measurement in water meters, other applications are energy consumption measurements, wind and speed measurements, etc. All common encoder types can be used: initiator according to NAMUR (DIN-EN 60947-5-6), 3-wire optical encoder, reed contacts, transistor outputs and other initiators .
