Counter Module FM 450-1

Intelligent counter modules for high-frequency counting task


The FM 450-1 intelligent counter module is an outstanding choice for a wide variety of high-frequency counting tasks up to 500 kHz. It has two counting channels, one for up counting and one for down counting.

The FM 450-1 acquires the pulses from incremental encoders in dependence on gate signals. It evaluates the direction of the pulses and compares the counter value with two programmable comparison values.
