Frequency signal normalisation module OM74301-C1 (IMES.421459.743-01)

The OM743 module is designed to normalise a signal in the form of unipolar or bipolar AC voltage of rectangular or sinusoidal shape with a constant component of frequency up to 10000 Hz. The OM743 module is installed in a contiguous set of Fastwel I/O peripheral modules, receives electrical power from the left- or right-handed blade contacts of the field power distribution included in the module, and converts four input signals of rectangular or sinusoidal form, fed to the front contacts 5, 6, 7, 8, into normalised rectangular signals, whose frequency values coincide with the frequency values of the input signals, with an amplitude of up to 30 V, transmitted to the module's output stages of the "open collector" type, connected to the front contacts 1, 2, 3, 4.
