Photo frequency generator HG G-57405

Frequency Generator in Top Hat Rail Casing

A frequency generator generates an alternating current in a conductive loop for guidance of driverless transport vehicles (FTF). The circuit board contains a generator with power amplifiers and a transformer for DC decoupling. The operating frequency can be selected via a HEX rotary switch with 16 positions.

Principle sketch inductive track guidance with frequency generatorSketch: Function

The generator generates a constant output current. Short circuits or too low load impedances as well as loop interruptions or too high load impedances are indicated by an LED on the front panel and a potential-free fault signal output. The frequency generator has separate connections for long or short loops. The maximum load impedance differs between long and short loops in a ratio of about 1:2. The loop current can be adjusted via a trimming potentiometer on the front panel.

Synchronization of generators

Up to 7 generators can be synchronized to avoid beatings when using the same frequencies. Further information can be found on the back.
