AD-FM 250 GVC

Description

The frequency measuring converter AD-FM 250 GVC supplies an initiator or a contact and transforms its impulse sequence to a proportional impressed analogue signal. The output signal is independent from the connected load up to a maximum value. Furthermore, this series of devices is equipped with a configuration interface AD-PC as standard, with which the input and output measuring signal can be freely programmed with the programming software AD-Studio. Input, output and the supply voltage are separated from each other galvanically with high isolation.
