Pulse Controller Module AMX-CTRL-4ED
Programmable Digital Pulse Controller for Power Switches 19"-AMX

Jump to: Technical Data Download

The pulse controller is a module that can be used to control up to four power switches and seven digital inputs/outputs. It integrates one digital oscillator and four digital pulse generators.

The symmetrical architecture of the pulse generators offers a large variability of configurations. The pulse generators can be chained to produce complex pulse sequences. They can be triggered periodically by the internal oscillator, by an external event, or by the software. Unused channels can be disabled.
